摘要: 通过自由基共聚合合成了含有高二阶非线性光学活性偶氮单元的侧链液晶共聚物。共聚物的液晶转变温度由DSC测定,实验证明当偶氮单元含量超过40mol%时,共聚物的液晶性消失。通过高压电场对该聚合物膜进行针尖电晕极化取向,并由紫外测试给出了聚合物膜的取向参数及其稳定性,对液晶聚合物的非线性光学性质进行了初步的研究。

Abstract: A zo-type nonmesogenic monomer and mesogenic monomer were synthesized.Copolymers were obtained using these monomers by radical polymerization.The phase transition temperatures of these copolymers were investigated by DSC,the result showed that the copolymer did not exhibit the mesomorphic nature in concentration of azo unit above 40 mol%.The polymeric film was poled by needle-electrode corona-onset poling at elevated temperature,the orientational order parameterφand its stability were estimated by UVmeasurement.This paper proceeded to an initial study for NLO property of liquid crystal polymer.
