| 摘 要： | 本文采用流延法制备出聚乙烯醇偏光膜,并用紫外可见分光光度仪分别对含碘及含碘、镍、钴的2种偏光膜的光学性能进行了研究。结果表明,偏光膜中加入镍、钴后,偏光膜的单片透光率增加,单片偏光系数及组合偏光率增加;垂直组合时,泄漏光的波峰值左移。

| Abstract: | Polarizing films were prepared by means of flowing method. Optical properties of the polarizing films containing iodine element and containing iodine, nickel and cobalt elements were studied by UV-range spectrophotometer. The results confirm that polarizing film containing nickel and cobalt has higher transmittance, single polarizing coefficient and combinational polarizing coefficient. When combined in perpendicular direction, the wave crest of leaking light moves left. |
