Abstract
The invention discloses a kind of polymer dispersed liquid crystal film and its manufacturing method based on macromolecule transparent conductive substrate, belongs to liquid crystal light modulation technical field.The polymer dispersed liquid crystal film, including polymer dispersed liquid crystal layer, first transparent PET layer and the first PEDOT conductive layer constitute the first PET-PEDOT conductive base, second transparent PET layer and the 2nd PEDOT conductive layer constitute the 2nd PET-PEDOT conductive base, polymer dispersed liquid crystal layer forms sandwich structure between the first and second PET-PEDOT conductive bases.The PET-PEDOT conductive base is the surface that PEDOT dispersion liquid is configured to PET base material by roller coating, then through macromolecule transparent conductive film made of high temperature oven heat drying, compared with traditional PET-ITO conductive base, PET-PEDOT conductive base making technology is simple, production cost is low, is provided simultaneously with ideal optically and electrically parameter.
Description
Technical field
The present invention relates to liquid crystal light modulation technical fields, and in particular to a kind of polymer based on macromolecule transparent conductive substrate
Dispersed liquid crystal film and its manufacturing method.
Background technique
Polymer dispersed liquid crystal film is otherwise known as pdlc film, intelligent light modulation film, intelligent fenestrated membrane etc., is by PDLC material and thoroughly
A kind of novel film material that bright compliant conductive substrate is obtained by modes such as coating roll-ins.Wherein PDLC material is then by liquid crystal
Composition is mixed with UV prepolymer, under certain condition aggregated reaction, is formed micron-sized liquid crystal droplet and is uniformly dispersed
In macromolecule network, the dielectric anisotropy of liquid crystal molecule is recycled to obtain the material with electro-optic response characteristic, it is main
Work is between scattering states and transparent state, and it is in unordered shape that in the case where no applied voltage, the arrangement of liquid crystal droplet optical axis is random
Mist state is presented in state, film；In the case where applying voltage, liquid crystal droplet optical axis vertical thin-film surface alignment is in order state, thin
Transparent state is presented in film.Liquid crystal molecule imparts the significant electro-optical characteristic of polymer dispersed liquid crystal film, it is made to receive extensive pass
Note, and have broad application prospects.For conventional display device, polymer dispersion type liquid crystal display device has very much
Advantage, such as polarizer and oriented layer are not needed, preparation process is simple, can be easily made large area flexible display etc., PDLC material
Material can be fabricated to light modulation film or dimming glass, by the induction to light and heat, adjust room temperature under voltage driving, reach section
Can environmental protection purpose, this technology electronic-control dimming glass, Projection Display, in terms of be widely applied.
Transparent flexible conductive base used in polymer dispersed liquid crystal film is made currently on the market mainly with poly- terephthaldehyde
The advantages of acetoacetic ester (PET) does tin indium oxide (ITO) film of substrate, abbreviation PET-ITO film, this conductive base is stability
Good, light transmittance height, sheet resistance are low, manufacture craft maturation etc., and the disadvantage is that ITO conductive material is needed by vacuum magnetic control sputtering process
It can be just uniformly distributed in pet sheet face, equipment investment is high with operating cost, and the scarcity of indium metal itself, leads to market in addition
Upper PET-ITO film price can not have always been high any more, this has raised the market price of polymer dispersed liquid crystal film in turn, strongly limit
Its application field, in consideration of it, it is existing to substitute to develop a kind of novel transparent flexible conductive base that can be used for pdlc film
PET-ITO substrate is necessary.
Inside all multi-parameters of pdlc film, the parameter of most critical is the ON state mist degree of diaphragm, this performance directly determines
The permeability of naked eyes perception and the size of visible angle under diaphragm energized state, contrast test discovery, at present finished product on the market
