Abstract
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.
