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.
