ABSTRACT:
A method for preparing electro-optical polymer-liquid crystal photonic crystals, comprising: disposing between at least two optically transparent electrode plates, a polymer-dispersed liquid crystal material that comprises, before exposure:(a) a polymerizable monomer comprising at least one acrylate;(b) a liquid crystal;(c) a chain-extending monomer;(d) a coinitiator;(e) a photoinitiator; and(f) a long chain aliphatic acid;and exposing this polymer-dispersed liquid crystal material to light in an interference pattern.
