聚合物网络结构决定了PNLC的光电性能。对聚合物单体的含量、聚合物单体的结构、液晶母体开展一系列实验。选用折射率大，负介电大的液晶，配合适合的聚合物单体含量和种类，并且优化聚合光照强度和温度控制，制备出关态响应速度低于1.85 ms，对比度5.54的高对比快速响应低压的PNLC。

The photoelectric properties of PNLC(polymer network liquid crystal) were determined by the structure of polymer network. A series of experiments were carried out on the ratio of polymer, the structure of polymer and the refractive index of liquid crystal. Conclusion is that refractive index , dielectric anisotropy of negative liquid crystal, kinds and ratio of polymer, polymerization conditions could all impact the photoelectric properties of PNLC. In the end, a fast response, low voltage, high contrast PNLC was proposed, whose response speed was less than 1.85 ms, and contrast was 5.54.
