Property Control of (Perfluorinated Ionomer)/(Inorganic Oxide) Composites by Tailoring the Nanoscale Morphology
Abstract
Unique perfluoro-organic/inorganic oxide hybrid materials have been formulated by merging processes recently developed by us for the solution and melting processing of perfluorosulfonate ionomers (PFSI's) and (2) the production of nanocomposites by the in situ sol-gel reaction for silicon and metal alkoxides within the polar clusters of PFSI's. Our working hypothesis is that the resultant morphology of the inorganic phased is ordered by the nanophase-separated morphology of the PFSI matrix. In this research, the 3- dimensional morphological template presented by the PFSI is tailored by manipulating the primary polymer structure, polymer solution conditions, film casting procedure, and post-processing (e.g. drying, annealing, melt-quenching, mechanical orientation). The nanocomposites are then characterized for microstructure broadly ranging from light microscopic resolution down to the level of Angstroms using various microscopic, scattering, diffraction and spectroscopic methods.
