Eyeglass and field lens composition are penetrated, the etching trace of galvanometer system uses linear type etching mode, the on-off of pulse laser and galvanometer system
The scanning range and process velocity of system are controlled and are set by computer program.
Utilize the contact angle on the super hydrophilic glass surface obtained described in the test of optical contact angle surface interfacial tension measuring instrument:
Using method measurement, the suspension drop of volume needed for being formed under liquid feeding syringe needle is picked up, the Z axis for adjusting processing platform makes sample surfaces
Rise, when the drop bottom hung under glass sheet surface and liquid feeding syringe needle contacts, drop is just transferred to glass from liquid feeding syringe needle
Then piece surface makes glass sheet surface drop to original position to measure by adjusting processing platform Z axis again, due to 3 micro-
Liter or more water droplet can direct invasion be paved with whole surface, the process that water droplet is uniformly spread can not be observed, thus drop volume be 2
Microlitre, test temperature is 23 DEG C, humidity 45%RH.
Shown in the contact angle schematic diagram such as Fig. 5 (5a) on the super hydrophilic glass surface and water that the implementation case is prepared, table
Shown in face pattern schematic diagram such as Fig. 5 (5b).
For the contact angle on super hydrophilic glass surface and water that the implementation case is prepared close to 0 °, test result is shown in Table 1.
Table 1

It can be seen that glass substrate surface by pulse laser etching processing of the invention close to 0 °, only
Change glass-faced construction, do not need using any coating or change its chemical composition, glass surface can be made to realize super hydrophilic,
And achieve the effect that automatically cleaning, antifog and good wetting property.Also have in medical field and be widely applied very much, such as in chemical examination blood
When liquid, using the good wetting property of super hydrophilic glass, blood can uniformly be sprawled around rapidly on super hydrophilic glass, solution
It has determined and has manually sprawled the problems such as uneven.And green and pollution-free, less energy consumption is laser machined, it is at low cost high-efficient, simultaneously
Fabrication process condition is wider, can obtain the stable super hydrophilic glass surface of performance by preparation, can process various types of
Glassware.
Super hydrophilic glass surface preparation method of the invention has the advantages that
(1) the laser preparation method simple process that uses of the present invention, only changes glass-faced construction, does not need using appointing
What coating changes its chemical composition；
(2) the method for the present invention is used, green and pollution-free, at low cost high-efficient, simultaneous processing process conditions are wider, fit
For processing the glassware of various shape and specification, stable super hydrophilic glass surface is prepared；
(3) the super hydrophilic glass surface being prepared using the method for the present invention, water droplet its surface contact angle close to
0 °, surface can sprawl rapidly, reach in the concave-convex of rule or the micro-structure of dimple-shaped, water droplet in uniform diffusion around
Super hydrophilic characteristic, plays critically important effect in practical application.
The foregoing is merely presently preferred embodiments of the present invention, is not intended to limit the invention, it is all in spirit of the invention and
Within principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
