| 摘 要： | 乙基氰乙基纤维素(E-CE)C]可溶解在丙烯酸(AA)中形成胆甾相液晶,通过光聚合AA,原胆甾相结构可以被"固定"在(E-CE)C/聚丙烯酸(PAA)复合物中,其结构和选择性反射光性能通过电镜和紫外-可见光光谱进行了研究.研究表明该复合物膜的反射光波长和浓度呈指数关系,反射光强度与膜厚有一定关系,并在低于160
℃时有很好的热稳定性.

| Abstract: | Ethyl-cyanoethyl cellulose (E-CE)C]/poly(acrylic acid) (PAA) composite films were prepared by photopolymerizing acrylic acid (AA) in (E-CE)C/AA cholesteric liquid crystalline solutions. Investigation of the structure and optical property of the (E-CE)C/PAA cholesteric composite and was undertaken by using UV-VIS spectroscopy and TEM. It was found that the wavelength of reflection light was a function of the concentration, the reflectivity was increased with increasing the film's thickness and was decreased quickly when temperature above 160 ℃. |
