METHOD OF FABRICATING A LIQUID CRYSTAL POLYMER FILM

摘要

A method of fabricating a liquid crystal polymer film includes providing a support substrate having a surface having a shape arranged to define a form of a liquid crystal polymer film to be fabricated; applying a layer of a photoaligning material over the surface of the support substrate, the photoaligning material having an absorption band; exposing the layer of photoaligning material to a light having a linear polarization and the light comprising a wavelength within the absorption band to convert the layer of photoaligning material into a layer of photoaligned material; applying a layer of a polymerizable liquid crystal over the layer of photoaligned material; performing photopolymerization of the layer of polymerizable liquid crystal to form a liquid crystal polymer film; applying a solvent to the layer of photoaligned material, the solvent formulated to dissolve the photoaligned material to thereby release the liquid crystal polymer film from the support substrate; and removing the liquid crystal polymer film from the support substrate.

1. A method of fabricating a liquid crystal polymer film, the method comprising:
(a) providing a support substrate having a surface having a shape arranged to define a form of a liquid crystal polymer film to be fabricated; (b) applying a layer of a photoaligning material over said surface of said support substrate, said photoaligning material having an absorption band; (c) exposing said layer of photoaligning material to a light having a linear polarization and said light comprising a wavelength within said absorption band to convert said layer of photoaligning material into a layer of photoaligned material; (d) applying a layer of a polymerizable liquid crystal over said layer of photoaligned material; (e) performing photopolymerization of said layer of polymerizable liquid crystal to form a liquid crystal polymer film of about 1 μm in thickness; (f) applying a solvent to said layer of photoaligned material, said solvent formulated to dissolve said photoaligned material to thereby release said liquid crystal polymer film from said support substrate; and (g) removing said liquid crystal polymer film from said support substrate.
