We study temperature driven anchoring transition in nematic/polymer composites as well as chiral nematic/polymer composites. Polymer dispersed liquid crystalline films are formed by photo-polymerizing the mixture of nematic fluid, monomer and crosslinking agent. As the photo-polymerization proceeds, the polymer polygonal cells that encapsulate the nematic liquid crystal. Since the anchoring behavior of liquid crystal is controlled by surface characteristics of the polymer, we modify and study the anchoring behavior by changing the length and branching of side groups
