Abstract
Commercial polyphenylsulfone was reacted with SiCl4 to afford a hybrid polymer and sulfonated to
different degrees using sulphuric acid or ClSO3Si(CH3)3. Polymers having different degrees of
sulfonation and different inorganic content were cross-linked via the formation of Si-O-Si bonds. The
products were characterized by ATR/FTIR spectroscopy 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 adequately high conductivity values to make them suitable candidates for application in
PEMFCs.
