摘　　要：从PDLC单体的优化、PDLC复合体系的掺杂和PDLC薄膜及智能玻璃系统的制造工艺3个方面对当前各个研究团队的研究成果进行了总结,其中单体方面含氧杂环等官能团和部分交联剂可以实现驱动电压的降低;碳纳米管和无机纳米材料等掺杂剂可以减小PDLC薄膜的阈值电压,并拓宽工作温度范围;电场的加入和反应时间的控制等也实现了对于PDLC系统的优化。但如何通过性能的提升实现PDLC智能玻璃在汽车窗等户外场景的应用仍需要更多的学者关注和研究。This article summarizes the research results of various research teams from three aspects,such as the optimization of polymer dispersed liquid crystal composite(PDLC)monomers,the doping of PDLC system,and the manufacturing processes for PDLC films and smart glass system.Monomers containing functional groups such as oxygen heterocycles and some cross-linking agents can reduce the driving voltage.Dopants such as carbon nanotubes and inorganic nanomaterials can reduce the threshold voltage of PDLC films and broaden the operation temperature range.The addition of electric field and the control of reaction time also achieve the optimization of PDLC system.However,the performance improvement ways to realize the application of PDLC smart glass in outdoor scenes such as car windows still need more attention and research from scholars.Simultaneously,the challenges and applications faced in expanding the application scenarios of PDLC films are discussed and prospected.
