大分子引发剂的分子量对聚合物分散液晶的微观形貌影响
Effect of Molecular Weight of Macroinitiator on Morphology of Polymer Dispersed Liquid Crystal
摘要
Abstract
The polymer dispersed liquid crystal (PDLC) films were prepared by photopoly-merization induced phase separation with macroinitiator (RAFT-PS) of different molecular weight, synthesized by RAFT polymerization. The influences of molecular weight of RAFT-PS on morphology, photopolymerization kinetics, nematic fraction and electro-optical properties of PDLCs had been investigated. It was found that the key factor of affecting morphology was not the molecular weight of polymer matrix and the rate of polymerization but the molecular weight of RAFT-PS. On the other hand, the diameter of liquid crystal droplets was effectively controlled by changing the molecular weight of RAFT-PS. This result contributed to improve electro-optical properties of PDLCs.关键词
