The invention relates to a
polymer dispersed
liquid crystal electronic paper and a manufacturing method thereof. A
composite film is constituted by two transparent flexible conductive films and a
polymer dispersed
liquid crystal layer, wherein, electrodes are etched on the two flexible transparent conductive films. A
polymer is modified
polyurethane acrylate which is added by a surfactant and
lecithin, and
liquid crystal is
dielectric switching liquid
crystal material which is the mixture of 20 percent
biphenyl ester and 80 percent difluoro
diphenylacetylene or the product with the same series. When a low-frequency
electric field is imposed on the polymer dispersed liquid
crystal electronic paper, the polymer dispersed liquid
crystal electronic paper is in the transparent open state, and the transparent open
station is still maintained after removing the
electric field; when a high-frequency
electric field is imposed, the polymer dispersed liquid crystal electronic paper is in the scattering
closed state, and the scattering
closed state is still maintained after removing the electric field. The manufacturing method of the polymer dispersed liquid crystal electronic paper is to form the weak anchoring polymer which is packaged by a
dielectric switching
liquid crystal droplet structure by separating after mixing the weak anchoring polymer with the
dielectric switching liquid crystal. The manufacturing method combines the natures of the weak anchoring polymer and the dielectric switching liquid crystal with the dual-frequency drive of low-frequency writing and high-frequency erasing so as to realize the stable zero-field of the polymer dispersed liquid crystal, thereby obtaining the new electronic paper technology or being applied as a new product of dimming glass.
