摘要
以1,4-二[4-(6-丙烯氧基己基)苯甲酰氧基]-2-甲苯(C6M) /(S)-4′-(2-甲基丁基)联苯-4-碳腈(CB15) /2,2-二甲基-1,2-二苯基乙烷(IRG651) / SLC1717为溶剂，采用紫外聚合诱导相分离法制备了反模式聚合物稳定甾醇结构(R-PSCT)薄膜。研究了固化温度和紫外辐照度对R-PSCT薄膜电光性能的影响。当固化温度升高或紫外辐照度降低时，驱动电压、对比度和导通响应时间降低，而关断响应时间增加。制备的R-PSCT薄膜固化温度为293 K，紫外辐照度为0。75 m W·cm- 2具有较好的光电性能。
Effects of preparing conditions on the electro-optical properties of reverse-mode polymer-stabilized cholesteric texture films
Reverse-mode polymer-stabilized cholesteric texture( R-PSCT) films were prepared from ultraviolet polymerization-induced phase separation in a mixture of 1,4-di[4-( 6-acryloyloxyhexyloxy) benzoyloxy]-2-methylbenzene( C6M) /( S)-4'-( 2-methylbutyl) biphenyl-4-carbonitrile( CB15) /2,2-dimethopxy-1,2-diphenyl-ethanone( IRG651) / SLC1717. The effects of curing temperature and ultraviolet( UV) irradiance on the electro-optical properties of R-PSCT films were studied. When the curing temperature increases or the ultraviolet irradiance decreases,the driving voltage,the contrast ratio and the on-state response time decrease,but the off-state response time increases. The R-PSCT film prepared at a curing temperature of 293 K and an ultraviolet irradiance of 0. 75 m W·cm- 2has better electro-optical properties.
期刊介绍：
Chinese Journal of Engineering Design is a reputable journal published by Zhejiang University Press Co., Ltd. It was founded in December, 1994 as the first internationally cooperative journal in the area of engineering design research. Administrated by the Ministry of Education of China, it is sponsored by both Zhejiang University and Chinese Society of Mechanical Engineering. Zhejiang University Press Co., Ltd. is fully responsible for its bimonthly domestic and oversea publication. Its page is in A4 size. This journal is devoted to reporting most up-to-date achievements of engineering design researches and therefore, to promote the communications of academic researches and their applications to industry. Achievments of great creativity and practicablity are extraordinarily desirable. Aiming at supplying designers, developers and researchers of diversified technical artifacts with valuable references, its content covers all aspects of design theory and methodology, as well as its enabling environment, for instance, creative design, concurrent design, conceptual design, intelligent design, web-based design, reverse engineering design, industrial design, design optimization, tribology, design by biological analogy, virtual reality in design, structural analysis and design, design knowledge representation, design knowledge management, design decision-making systems, etc.
