摘要
采用摩擦表面取向层的方法制备了有光学各向异性结构的PDLC膜。研究了液晶盒的厚度、摩擦强度,以及在紫外光诱导相分离过程中的光照强度对PDLC膜的光学各向异性程度和电光特性的影响。对PDLC的光学各向异性进行了研究,并给出了要获得低阈值电压、高各向异性的聚合物分散液晶各向异性膜的盒厚、摩擦强度以及光照强度等条件。被取向后的PDLC各向异性膜可被用来作为具有很好光电特性的电可调散射式偏振片。
Optically anisotropic PDLC films have been induced by antiparallely rubbed surface alignment layer. It is found that optically anisotropic properties of PDLC film are greatly depended on the cell thickness, rubbing strength and phase separation process. Optically anisotropic PDLC films can be acted as scattering polarizers with optimal electro-optical properties. The optical anisotropy characters of oriented PDLC films are analyzed. The cell thickness, rubbing strength and UV light intensity are analyzed for obtaining optimum anisotropic PDLC film with low threshold voltage and high contrast ratio.
