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。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.
