| 摘 要： | 以Ar+激光器为光源, 采用虎红、 N-苯基甘氨酸、二季戊四醇羟基五丙烯酸酯和乙烯基吡咯烷酮分别作为光引发剂、共引发剂、预聚物和稀释剂, 与液晶材料TEB30A结合, 通过光聚合反应, 制备了聚合物分散液晶(PDLC), 用紫外光谱和荧光光谱对其反应机理进行了分析. 实验结果表明, PDLC是通过光引发剂吸收光子能量后与共引发剂相互作用, 形成自由基中间体并引发聚合反应, 使预聚物与液晶产生相分离形成的. |

| Abstract: | Polymer dispersed liquid crystal(PDLC )has extensive applications in non-linear optical material, displays and optical attenuation devices. In this paper, Ar+ laser was used as radiation source and Rose Bengal, N-phenyl glycine(NPG), dipentaerythrol hydrixy penta actylate, 1-viny-2-pyrrolidone were applied as photoinitiator, coinitiator, pre-polymer, thinner respectively to prepare PDLC with liquid crystal TEB30A. Ultraviolet spectra and spectrofluorimetry were applied to analyze the mechanism of the photo-... |
