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。

A Thermally switchable and flexible LCDs:A PDCLC sample is irradiated with a UV light through a photo-mask having the desired patterns, the CLC texture in the UV-cured region is changed from reflective planar texture to the scattered focal conic one. Additionally, the clearing temperature of the LCs in UV-cured regions is higher than that in uncured regions. Therefore, if the cell temperature is lower than Tuc-I (Tuc-I and Tc-I), the scattered patterns are displayed on the reflective background. Moreover, the addressed patterns are invisible when the cell temperature increases higher than Tc-I.

利用紫外光经过透射光罩写入图像，使聚合区域为散射之focal conic态，且该区域之相变温度较未照光区域高，故低於Tuc-I时，散射的focal conic图像显示於反射的planar结构背景上；而介於Tc-I及Tuc-I之间时，散射的focal conic图像显示於穿透的isotropic态背景上；若温度高於Tc-I时，图像与背景皆是isotropic态，亦即关闭显示图像。

C Thermally controllable light valves:As described above, the clearing temperature of PDCLCs can be increased by UV-curing because of the reduction of impurity concentration. Therefore, when the texture of a CLC cell in the UV-cured region are changed to focal conic one, the scattering of light from the sample is maximum. However, the clearing temperature of PDCLCs can be increased continually with continually irradiating with UV light onto the sample, but the scattering is unchanged.

当PDCLC照射紫外光的时间超过某一特定时间，则表面配向被聚合物薄膜破坏而达成散射态之穿透度最低状态，若持续照光聚合时，因仍然处於focal conic态，故穿透度不再改变，但单体聚合造成相变温度上升，直到单体全部聚合为止。

The results show that the density of gritstone is decreased gradually as the temperature increasing; so that it can be ignored; the longitudinal wave velocity is linearly decreased when the temperature increasing, and decrease rate of it follows the law of conic; R is one temperature point, which makes the law of tensile strength of gritstone after high temperature follows the law of parabola; and the maximal tensile strength appears when the operative temperature is R. After the temperature is higher than 700 ℃, tensile strength is small and change range is small when the temperature is increased.
