摘要： 通过溶胶-凝胶法制备了含二阶非线性光学发色团分散红19(DR19)的硅氧烷染料与聚酰亚胺有机-无机杂化材料.利用红外光谱、紫外-可见光谱、SEM、DSC和TGA等手段对其进行了表征.杂化极化后的序参数高达0.48,并具有优良的极化取向稳定性,423K下处理300h后,序参数仍能保持初始值的90%.杂化薄膜有较好的表面平整性,其断面呈网络结构.杂化材料的玻璃化转变温度(Tg)为561K,比纯聚酰亚胺的Tg(543K)高18K,表现出优良的高温热稳定性,其5%热失重温度为691K,10%热失重温度为758K.

Abstract: Asecond order nonlinear optical(NLO) organic/inorganic hybrid polyimide was successfully prepared by sol gel process, and was characterized by FTIRspectroscopy, UV-Vis spectroscopy, SEM, DSCand TGA. The order parameter of the hybrid material after the polarization is 048 and it maintains 90% of the initial value after the treatment for 300 h at 150 ℃. The SEManalysis shows that the surface of the hybrid thin film is very smooth, and cross-linking structure is observed in the cross section. The Tg of the polyimide/inorganic hybrid material(561 K) is higher than that of the corresponding pure polyimide(543 K). The sol gel hybrid thin film also exhibits a good thermal stability, with 5% and 10% weight loss temperatures at 691 and 758 K, respectively.

Key words: Organic/inorganic hybrid material, Polyimide, Second order nonlinear optical material
