Title: Nonlinear optical materials: Synthesis, characterizations, thermal stability and electro-optical properties

Abstract

Two series of thermal stable polyimides and polyimide/silica hybrid materials have been synthesized. The silica content in the hybrid materials was varied from 0 to 22.5 wt.% and SiO{sub 2} phase was well dispersed in the polymer matrix. The glass transition temperature (T {sub g}) and the decomposition temperature (T {sub d}) were in the range 226-382 deg. C and 345-499 deg. C, respectively, for materials. The polymer solutions could be spin coated on the indium-tin-oxide (ITO) glass or other substrates to form optical quality thin films. The electro-optic coefficients ({gamma} {sub 33}) at the wavelength of 832 nm for polymer thin films poled were in the range of 12-25 pm/V and the values remained well (retained > 85% for more than 100 h). The heat capacities of some materials were in the range of 0.9755-1.1821 J K{sup -1} g{sup -1} for the temperature 273 and 363 K. No thermal anomaly was found in this temperature range. Most of them showed high thermal stability.
