摘要
针对聚合物分散液晶(PDLC)二元体系进行了研究,主要包括外加直流电场下制备的PDLC的相图研究以及PDLC形成过程中相分离情况。在PDLC制备过程中由于外加直流电场对小分子液晶的作用,使液晶在此二元结构中的清亮点发生变化。结果表明,直流电场的引入导致PDLC中液晶清亮点升高。相分离行为主要是跟踪PDLC形成过程中由于小分子液晶与高分子链段之间的排斥作用而引起的相分离,研究了不同条件下PDLC相分离的快慢。
The polymer dispersed liquid crystal (PDLC) film was prepared and its binary structure was studied, which including the phase diagram of the PDLC prepared under the electric field and the phase separation of PDLC. Due to the effect of electric field to the liquid crystal, if an electric field is applied in the polymerization induced phase separation, the clear point of the liquid crystal will change distinctly. Phase separation is induced by the repellency between the liquid crystal and polymer chain. it can be detected by the DLI Technique.
