中文摘要：

以甲基丙烯酸B羟乙酯为聚合单体，以SLC7011—100为液晶材料，利用紫外光聚合分相法制备了PDLC薄膜。通过调节单体和液晶成分的比例，在尽可能提高膜的对比度的情况下降低驱动电压，以获得电-光性能良好的PDLC膜。分别向体系添加壬烷氧基和癸烷氧基联苯氰基液晶、烷基联苯氰基类液晶5CB和8CB，考察了PDLC膜电-光性能的变化，结果表明，添加液晶的含量和分子结构对PDLC膜的折射率、对比度等电-光性能参数有较大影响。

英文摘要：

Polymer-dispersed liquid crystal （PDLC） films were prepared by using β-hydroxyethyl acrylate and SLC 7011-100 as starting monomer and liquid crystal （LC）, respectively, via polymerization-induced phase separation. To decrease driving voltage while keeping a high con- trast ratio and obtain a PDLC film with good electro-optical properties, various ratios of monomer and LC were tested. Investigation of the relationship between LC and electro-optical properties suggests that the content and molecular length of the LC added have large effect on the parameters of electro-optical properties such as reflective index and contrast ratio.
