Abstract

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.
