For this study, we first prepared a fluorocarbon polymer and its hybrid materials. We found that fluorocarbon copolymers can produce hydrogen bonds with Sio(2) to form hybrid materials. We also used thermogravimetric analyzer and tested the thermostabilities of the four products, which were ranked as follows: fluorocarbon copolymer/SiO2 hybrid material > fluorocarbon polymer/SiO2 hybrid material > fluorocarbon copolymer > fluorocarbon polymer. In addition, we found that, due to the inorganic SiO2 used, the number of pores and the specific surface areas of the hybrid materials both increased. (c) 2006 Wiley Periodicals, Inc.
