摘要

合成了一种活性大分子试剂

将其引入聚合诱导分相法中

研究了其含量和光引发剂含量对PDLC光电性能的影响。结果表明:随着活性大分子试剂和光引发剂含量的上升

PDLC的关态透光率明显下降

阈值电压及饱和电压有所上升。文章对活性大分子试剂在聚合过程中的作用机理进行了分析。

Abstract

PDLC films were prepared with the method of PIPS(photo polymerization induced phase separation) by macro-initiator prepared by RAFA(reversible addition fragmentation chain transfer).The effect of RAFT-M on electro-optical properties of PDLC films was investigated. It was found that as the RAFT-M and photo initiater increased

both the threshold voltage and saturation voltage increased

and both the off-state transmittance and the on-state transmittance decreased.
