Abstract
Hydroxyl-containing fluorinated polyimide-silica hybrid materials (FPI-SiO 2 ) were obtained using the sol-gel technique by polycondensation of tetramethoxysilane (TMOS) in 3-aminopropylmethyl diethoxysilane (APrMDEOS)-terminated amic acid solution. Infrared, 29 Si-, and 13 C-NMR spectroscopy and thermogravimetric analysis (TGA) were used to study hybrids containing various proportions of TMOS. The microstructure and chain mobility of the hybrids was investigated by spin-lattice relaxation time in rotating frame ( T^{H}_{1\\rho} ) measurements. The apparent activation energy (E a ) for degradation of the hybrids was studied by Friedman and van Krevelen methods.
