Abstract
Polymer blended membranes which comprise a blend of a compound such as a heteropoly acid or salt thereof and a polymer which is at least partially compatible with said compound, said blend containing a multiplicity of electrically conductive particles which form a portion of said membrane may be prepared by admixing the polymer and the acid or salt in a mutually miscible solvent. Thereafter, the electrically conductive particles, the size of which is sufficient so that the surfaces of the particles are coexistent with or extend beyond the surfaces of the membrane, may be added to the solution or, alternatively, the solution may be cast onto a casting surface and the particles added in a manner so as to ensure a uniform distribution of the particles throughout the solution. After evaporation of the solvent, the resulting thin film membrane may then be recovered and used in a gas separation apparatus or in a gas sensor apparatus.
