碩士 === 元智大學 === 化學工程研究所 === 89 === Under the cholesteric phase, the composite of HPPB/E7/CB 15 has a special elect optical effect. Under the room temperature, we find some beautiful colors by electric field without polarizer. It tells us that the kind of liquid crystal phase has the selected absorptive and visible light wavelength behavior. Then we mixed it with Pdi-iPF and compare with the unmixed one. The composite of HPPB/E7/C15 can be achieved the light scattering and light opaque by thermal transmission, and it makes the different contrast of the liquid crystal panel with different temperature.
