Abstract

Experimental work was carried out aimed at producing composite membranes possessing high permeation rate and high thermal stability. Such composite membranes were prepared by supporting different siloxane polymers on porous anodic aluminum oxide film; they were then subjected to permeation experiments with H2, He, N2, O2 and CO2 gases at various temperatures. The permeation characteristics of the membranes were found to be controlled by permeation in the polymers. High thermal stability was exhibited by the composite membranes. Poly(methylsiloxane) composite membranes were usable up to 200°C and showed the highest permeation rate, which was at least ten times that of commercial silicone polymer membranes. The permeation characteristics of the composite membranes are discussed in connection with the correlation of gas solubilities in the siloxane polymers.
