摘要
制作出一种厚度为30μm的手性E型胆甾相液晶薄膜,通过原子力显微镜测试显示其螺距为364nm。使用He-Ne激光对其出射光的偏振特性及左右圆偏振光透射特性进行测试,结果表明手性E型胆甾相液晶表现出较强的左圆偏振光透射特性,其左右圆偏振光透射比为1∶0.4。
<Abstrcat>The chiral polymer cholesteric liquid crystal-E film which thickness was 30μm has been manufactured successfully. The test of AFM shows that the pitch of chiral polymer cholesteric liquid crystal-E is 364nm. He-Ne laser is used to measure the polarization of output light and the transmitting characteristic of left-right polarized light. The result shows that the transmitting of left polarized light of the chiral polymer cholesteric liquid crystal-E film is rather strong. The ratio of left-right polarized light transmission is 1 to 0.4.
