本論文主要目的為液晶聚合物的鍵結研究，RM257為一款可光聚合的液晶聚合物。在之前的研究中，RM257常常利用UV光來啟動分子進行聚合反應，RM257單體分子兩端具有光活性官能基，單體互相鍵結形成網絡高分子。在本研究中，我們使用氦氖雷射為進行RM257的聚合反應之光源。
利用氦氖雷射對低濃度光聚合物的液晶樣品進行曝光，我們發現電壓的高低以及液晶配向類型，會對聚合物的聚合及鍵結有一定程度的影響。由於之前的研究中較少出現吸收波段在紅光波段的起始劑，H-Nu-Blue 640是一款吸收波段約在570~670奈米波長的起始劑，本研究中將會使用低濃度起始劑、低濃度光聚合物的樣品作研究。

This thesis is mainly about liquid crystalline and polymer bonds,RM257 is a diacrylate material which is able polymerize through light exposure. At previous research ,diacrylate is often polymerized through UV light exposure. RM257 mesogen have photopolymeriable acrylate endgroups. RM257 molecules form to polymer network.In this research, we use He-Ne laser as the light source to do RM257 polymerization.
At first, we use He-Ne laser to do the research of interference. During research, we found that the difference of applying voltage and liquid crystal orientation will change the expose time of polymer bonds.
The previous researches are not using red light initiator, H-Nu-Blue 640 is a initiator which has the max absorbance in the 570~670 nm range, this research will also concern about the affection of initiator to polymer bonds.
