See also Fig. 6, in the present embodiment, the adhesive-layer 13 that solidify said first area 132 forms the bar paten that a plurality of intervals are provided with respectively with second area 134 uncured adhesive-layers 13.The adhesive-layer 13 of present embodiment is a UV glue-line, and the method for its curing specifically may further comprise the steps:
At first, a mask 15 is set above said adhesive-layer 13.
The said mask 15 unsettled surfaces that are arranged at said adhesive-layer 13 away from substrate 12.The shape of said mask 15 and carbon nanotube layer 18 selections of size according to institute's patterning that will prepare.Particularly, said mask 15 comprises a body 150, and this body 150 is provided with through hole 152.Said through hole 152 is the transmittance section, and said body is a light-blocking part.The centre position that said transmittance section can be positioned at light-blocking part also can be positioned at the marginal position of light-blocking part.Because the effect of mask 15, said adhesive-layer 13 is first area 132 corresponding to the zone definitions of transmittance section, is second area 134 corresponding to the zone definitions of light-blocking part.In the present embodiment, said mask 15 is one to have the baffle plate of a plurality of bar shaped perforates.

At last, remove said mask 15.
Step 4 forms a carbon nanotube layer 14 on adhesive-layer 13 surfaces.
Said carbon nanotube layer 14 is made up of some CNTs, and the bearing of trend of most of CNTs is basically parallel to the surface of this carbon nanotube layer 14 in this carbon nanotube layer 14.The thickness of said carbon nanotube layer 14 is not limit, and can select as required; The thickness of said carbon nanotube layer 14 is 0.5 nanometer ~ 100 micron; Preferably, the thickness of this carbon nanotube layer 14 is 100 nanometers ~ 200 nanometers.Because the even carbon nanotube in the said carbon nanotube layer 14 distributes and has good flexible, makes this carbon nanotube layer 14 have good flexible, can bending fold become arbitrary shape and be difficult for breaking.
CNT in the said carbon nanotube layer 14 comprises one or more in SWCN, double-walled carbon nano-tube and the multi-walled carbon nano-tubes.The diameter of said SWCN is 0.5 nanometer ~ 50 nanometers, and the diameter of double-walled carbon nano-tube is 1.0 nanometers ~ 50 nanometers, and the diameter of multi-walled carbon nano-tubes is 1.5 nanometers ~ 50 nanometers.The length of said CNT is greater than 50 microns.Preferably, the length of this CNT is preferably 200 microns ~ 900 microns.
Unordered or the orderly arrangement of CNT in the said carbon nanotube layer 14.So-called lack of alignment is meant that the orientation of CNT is random.The so-called arrangement in order is meant that the orientation of CNT is regular.Particularly, when carbon nanotube layer 14 comprised the CNT of lack of alignment, CNT twined each other or isotropism is arranged; When carbon nanotube layer 14 comprised orderly carbon nanotubes arranged, CNT was arranged of preferred orient along a direction or a plurality of directions.So-called " preferred orientation " is meant that the most of CNTs in the said carbon nanotube layer 14 have bigger orientation probability on a direction or several direction; That is, the axially basic of the most of CNTs in this carbon nanotube layer 14 extended along same direction or several direction.Have the gap between the adjacent CNT among the said carbon nanotube layer 14, thereby in carbon nanotube layer 14, form a plurality of gaps.
In the present embodiment, said carbon nanotube layer 14 comprises at least one carbon nano-tube film.When said carbon nanotube layer 14 comprised a plurality of carbon nano-tube film, this carbon nano-tube film can be provided with or range upon range of setting by substantially parallel no gap coplane.See also Fig. 7, the self supporting structure that said carbon nano-tube film is made up of some CNTs.Said some CNTs are arranged of preferred orient along same direction.The whole bearing of trend of most of CNTs basically in the same direction in this carbon nano-tube film.And the whole bearing of trend of said most of CNTs is basically parallel to the surface of carbon nano-tube film.Further, most CNTs are to join end to end through Van der Waals (Van Der Waals) power in the said carbon nano-tube film.Particularly, each CNT joins end to end through Van der Waals force with adjacent CNT on bearing of trend in the most of CNTs that extend basically in the same direction in the said carbon nano-tube film.Certainly, have the CNT of minority random alignment in the said carbon nano-tube film, these CNTs can not arranged the overall orientation of most of CNTs in the carbon nano-tube film and constitute obviously influence.Said carbon nano-tube film does not need large-area supported; And as long as the relative both sides power of providing support can be unsettled on the whole and keep self membranaceous state; When being about to this carbon nano-tube film and placing on two supporters that (or being fixed in) be provided with at interval, the carbon nano-tube film between two supporters can the membranaceous state of unsettled maintenance self.
Particularly, the most CNTs that extend basically in the same direction in the said carbon nano-tube film, and nisi linearity, bending that can be suitable; Perhaps be not fully according to arranging on the bearing of trend, can be suitable depart from bearing of trend.Therefore, can not get rid of between the CNT arranged side by side in the most CNTs that extend basically in the same direction of carbon nano-tube film and possibly have the part contact.
Particularly, said carbon nano-tube film comprise a plurality of continuously and the CNT fragment that aligns.These a plurality of CNT fragments join end to end through Van der Waals force.Each CNT fragment comprises a plurality of CNTs that are parallel to each other, and these a plurality of CNTs that are parallel to each other are combined closely through Van der Waals force.This CNT fragment has length, thickness, uniformity and shape arbitrarily.CNT in this carbon nano-tube film is arranged of preferred orient along same direction.
Be appreciated that through a plurality of carbon nano-tube films are parallel and do not have that the gap coplane is laid or/and range upon range of laying, can prepare the carbon nanotube layer 14 of different area and thickness.The thickness of each carbon nano-tube film can be 0.5 nanometer ~ 100 micron.When carbon nanotube layer 14 comprised the carbon nano-tube film of a plurality of range upon range of settings, the orientation of the CNT in the adjacent carbon nano-tube film formed an angle, 0≤α≤90.
Said carbon nano-tube film can be through directly pulling acquisition from carbon nano pipe array.Particularly, at first on the substrate of quartz or wafer or other material, grow carbon nano pipe array, for example use chemical gaseous phase Shen to amass (Chemical Vapor Deposition, CVD) method; Then, with stretching technique CNT is pulled out from carbon nano pipe array one by one and formed.These CNTs are able to by Van der Waals force join end to end, and form the conductive elongate structure that tool certain orientation property and almost parallel are arranged.Formed carbon nano-tube film can be in the minimum electrical impedance of the direction tool that stretches, and perpendicular to the maximum electrical impedance of draw direction tool, thereby possess electrical impedance anisotropy.
Said carbon nanotube layer 14 can be formed at adhesive-layer 13 surfaces through methods such as printing, deposition or direct layings.In the present embodiment, said carbon nanotube layer 14 is one to have the carbon nano-tube film of self-supporting effect, and it can directly be layed in whole adhesive-layer 13 surfaces.Be appreciated that through parallel no gap a plurality of carbon nano-tube films being set can be spliced into large-area carbon nanotube layer 14.
After carbon nanotube layer 14 is formed at adhesive-layer 13 surfaces; Because being positioned at the part of first area 132, adhesive-layer 13 has cured; Only be formed at adhesive-layer 13 surfaces so be positioned at the carbon nanotube layer 14 of first area 132, and combine with the adhesive-layer 13 of curing through Van der Waals force.Therefore, the said carbon nanotube layer that is positioned at first area 132 14 is fainter with the adhesion of adhesive-layer 13.Because it is still uncured that adhesive-layer 13 is positioned at the part of second area 134, can partly or entirely soak into adhesive-layer 13 so be arranged in 14 of the carbon nanotube layers of second area 134, and combine with adhesive-layer 13 through cohesive force.Therefore, the said carbon nanotube layer that is positioned at second area 134 14 is more firm with the adhesion of adhesive-layer 13.Preferably, the said CNT that is arranged in the carbon nanotube layer 14 of second area 134 partly soaks into adhesive-layer 13, and part is exposed to outside the adhesive-layer 13.
Further, soak into adhesive-layer 13, can also comprise the step of this carbon nanotube layer 14 of extruding in order to make the carbon nanotube layer 14 that is arranged in second area 134.In the present embodiment, adopt a PET film to be layed in carbon nanotube layer 14 surfaces, this carbon nanotube layer 14 of extruding gently.
Step 5 is solidified adhesive-layer 13, makes the adhesive-layer 13 of second area 134 fixing with carbon nanotube layer 14 bondings.
The method of said curing adhesive-layer 13 is identical with local solidification adhesive-layer 13 methods, need select according to the material of adhesive-layer 13.The step of said curing adhesive-layer 13 is actual to be cured for the uncured portion that adhesive-layer 13 is positioned at second area 134.Soak into adhesive-layer 13 owing to be arranged in the carbon nanotube layer 14 of second area 134, can be fixed in the process that adhesive-layer 13 solidifies so be arranged in the carbon nanotube layer 14 of second area 134 in this step.And the adhesive-layer 13 that is positioned at first area 132 has cured, can be unfixing by adhesive-layer 13 so be positioned at the carbon nano-tube film of first area 132.In the present embodiment, the method through UV-irradiation makes the UV adhesive curing that is positioned at second area 134.
Step 6 is removed the carbon nanotube layer 14 that is positioned at first area 132, forms the carbon nanotube layer 18 of patterning, thereby obtains pattern conductive element 10.
Said removal is positioned at the method for the carbon nanotube layer 14 of first area 132 and can peels off or peel off through cleaning roller for boning through adhesive tape.Said cleaning roller surface has certain viscosity, can carbon nanotube layer 14 clung and peel off.Because the carbon nanotube layer 14 that is positioned at first area 132 only combines with adhesive-layer 13 through Van der Waals force, with adhesive-layer 13 surface combination power a little less than, so bond or the cleaning roller rolling can be easily with these part carbon nanotube layer 14 removals through adhesive tape.In the present embodiment, will be positioned at carbon nanotube layer 14 removals of first area 132 through the method for adhesive tape bonding.Because present embodiment makes the adhesive-layer 13 that is positioned at first area 132 solidify earlier, the back forms carbon nanotube layer 14, so greatly reduce the difficulty of the carbon nanotube layer 14 of removing first area 132.Certainly, remove the carbon nanotube layer 14 that is positioned at first area 132 and can also take other modes, such as laser ablation, particle beams etching or electron beam lithography etc.
Pattern conductive element that the embodiment of the invention provides and preparation method thereof has the following advantages: first; CNT has excellent mechanical characteristic makes carbon nanotube layer have good toughness and mechanical strength; And anti-bending; So adopt carbon nanotube layer as transparency conducting layer, can improve the durability of transparency conducting layer accordingly; Second; Because carbon nanotube layer comprises a plurality of equally distributed CNTs, so this carbon nanotube layer also has uniform resistance and distributes; Therefore; Adopt this carbon nanotube layer can improve the electronic equipment that uses this transparency conducting layer accordingly as transparency conducting layer, like touch-screen, sensitivity and accuracy; The 3rd, through first local solidification adhesive-layer, form again carbon nanotube layer method can so that carbon nanotube layer to be removed do not fixed by adhesive-layer, thereby reduced the difficulty of removing carbon nanotube layer.Compare with the laser ablation carbon nanotube layer, this method not only technology is simple, and is with low cost, and improved the efficient of preparation pattern conductive element.The 4th, because having self-control, carbon nano-tube film becomes second nature, so can directly be layed in the adhesive-layer surface, preparation technology oversimplifies.
In addition, those skilled in the art can also do other and change in spirit of the present invention, and these all should be included in the present invention's scope required for protection according to the variation that the present invention's spirit is done.
