摘要：

Lithium salts-containing hybrids were prepared by hydrolysis-condensation of tetramethoxysilane (TMOS) in solution in N,N-dimethylacetamide(DMAc) containing 10 wt% trifluoromethanesulfonate (LiCF3SO3) and (3-aminopropyl)methyl diethoxysilane (APrMDEOS) terminated amic acid. Infrared (IR), Si-29 and C-13 CP/MAS nuclear magnetic resonance (NMR) spectroscopy, thermo-mechanical analysis (TMA), and thermogravimetric analysis (TGA) were used to study various hybrids. The spin-spin relaxation time T-2 of the hybrid was studied to probe the role of the salt. The apparent activation energy E-a for degradation of hybrids in air was evaluated by the van Krevelen method. (C) 2000 Elsevier Science Ltd. All rights reserved.
