摘要
以聚甲基丙烯酸甲酯及其改性物聚酰亚胺作为膜的基体，与向列型混合液晶ＧＲ－６３制成复合膜及其液晶盒。通过ＤＳＣ和扫描电子显微镜考察了复合膜的组分间相互作用及复合膜的相分离结构，并且研究了以该复合膜所制成的液晶盒的某些光开关性质及其相应的影响因素。
We studied the electro-optical properties of a PDLC(polymer dispersed liquid crystals)film composed of a nematic liquid crystal mixture GR-63 dispersed as droplets in either polymethyl methacrylate(PMMA)or its modified resin polymethacrylic imide(PMI)matriX. The phase-seperated structure of the compeite films have been investigated by means of differential scanning calorimetry(DSC)analysis and scanning electron microscope.On the basis of the above measurements, we nave discussed certain factorw affecting light scattering-light trasmission switching of the PDLC composite films.
