In-situ fabrication of microscopic photoalignment polymer film by the inkjet printing

Abstract

Liquid crystalline polymers (LCPs) with N-benzylideneaniline (NBA) side groups containing fluorine are synthesized by in-situ reaction of polymethacrylate with benzaldehyde side groups and phenylamine monomeric derivatives with fluorine in the film. Inkjet coating of phenylamine derivative achieves patterned photoinduced orientation of the resultant films.
