Polymer matrix composites are prepared by incorporating a highly conjugated substituted polyacetylene into a Nafion ionomer membrane. The monomer, 2-ethynylpyridine (2EP) is quaternized within the ionic domains of Nafion. An in-situ polymerization occurs upon heating the membranes which contain 5-15% by weight of 2EP. Dynamic mechanical analysis and thermogravimetric analysis studies indicate that the mechanical properties and thermal stability of the composites are superior to Nafion. Gas permeability coefficients of O2 and N2 are measured. Preliminary results indicate significant increase in the separation factor (α = PeO2/PeN2) within the composite.
