本文研究了预聚物和液晶在不同混合浓度配比条件下制备的PDLC膜的电光特性。实验发现,在适宜范围内的浓度配比可制备出较好电光特性的样品。并在这个浓度配比的范围内,用掺有一定比例的二向性染料明显地改善了PDLC膜的对比度。
In this paper, the electro-optic properties of PDLC films prepared by prepolymer and liquid crystal under different mixing concentrations were studied. The experiment found that in the appropriate range of concentration ratio can be prepared better electro-optical properties of the sample. And in the range of concentration ratio, doping with a certain proportion of dyestuff significantly improved the PDLC film contrast.
