This thesis demonstrates the pre-polymers in a polymer-dispersed cholesteric liquid crystals can be polymerized into a polymer film, which can eliminate the aligning capability of the homogeneous alignment layer. Thereafter, the textures of the cholesteric liquid crystals in UV-cured region can be changed from reflective planar texture to the scattered focal conic one. Additionally, the clearing temperature of the liquid crystals can be reduced by doping with chiral dopant or monomers. The cause is the increase of the impurity concentration in LCs. In other words, if the monomers are polymerized, the clearing temperature of LCs in that region should increase due to the decrease of the impurity concentration. Therefore, impurities associated with doping with monomeric and chiral dopants cause the clearing temperature of LCs in cured region to differ from that in uncured region.

本文中，我们提出在高分子聚合物薄膜之胆固醇液晶(polymer-dispersed cholesteric liquid crystals，简称PDCLCs)中，利用紫外光使PDCLC中的单体聚合成薄膜，此即为光引致聚合反应，而该薄膜将原本在表面所作的配向膜覆盖且破坏其配向能力，使胆固醇液晶由原本反射的planar结构转换成散射的focal conic结构；另外，有关液晶材料的相变温度会由於掺杂手性分子或单体而降低，此因液晶材料内『杂质』浓度增加，而造成的液晶材料之不纯度增加，最终导致相变温度降低，若搭配上述光引致聚合反应，则由於光照区之单体聚合，使该区域单体占总材料之比例下降，即不纯度降低，进而使液晶材料之相变温度上升，该区域之相变温度与未照光区有所不同。

It was found that the composite structure of Ti-Si-N films, nanocrystalline TiN embedded in amorphous Si_3N_4 matrix, was confirmed in this work. The increasing deposition pressure resulted in the appearance of columnar structure, decrease in the film density, increase in the surface roughness, and deterioration of the adhesion strength and tribological properties.

产生光油薄膜雾化条件正常情况下，上光油一般不会产生雾化，例如用户在香烟盒表面往往在表面再覆一层聚烯烃薄膜后，湿度大、特别是气温高到一定条件时，当底油涂布后，面油往往因极短暂的气雾致使光油附着牢度不好，而覆在上光油表面的聚烯烃薄膜就会出现浓浓的均匀的雾状小蒸汽，这时反而降低或导致商品的肉质的变化。
