    Notes: Abstract Ceramers based on silica and bisphenol-A epoxy resin cured with methyl nadic anhydride (MNA) and diamino diphenyl sulphone (DDS) were prepared in THF solutions. Compatibilization was induced through functionalization of the epoxy resin with amine trialkoxy silanes prior to mixing with a pre-hydrolyzed tetralkoxysilane solution (TEOS). The epoxy ceramers were further modified by the addition of small amounts of a silane functionalized alkane perfluoroether oligomer. A morphology consisting of very fine interpenetrating phases could be easily achieved through the silane functionalization of the epoxy resin. The final ceramer, however, always displayed a reduction in the glass transition temperature (Tg), resulting either from reactions of the anhydride hardener with the ethanol produced from the hydrolysis of TEOS or from the reaction of the acid catalyst with the epoxy groups. The use of the perfluoroether oligomer produced a large reduction in surface energy due to migration of the fluorinated components to the outer layers of the films.
