Abstract

Commercial polyether-etherketone was sulfonated and reacted with SiCl 4 to obtain a hybrid polymer. Polymers having different inorganic content were characterized by 29Si NMR, ATR/FTIR spectroscopies and mass spectrometry (FAB-MS) demonstrating the formation of covalent bonds between the organic and inorganic components and the absence of dispersed inorganic silicon. The physicochemical properties of the hybrids were suitable for the preparation of membranes which showed sufficiently high conductivity values to make them promising candidates for application in PEMFCs.
