摘要

Matrimid is a widely used polyimide that has both attractive thermal and gas transport properties.In addition,it has been used as a precursor polymer for production of carbon molecular sieving membranes with commercially interesting gas separations.Ion beam irradiation over a wide range of doses wasused to modify a series of Matrimid membranes.A combined analysis of impact of ion irradiation on the chemical structure,microstructure and gas transport propertiesof Matrimid will be presented.Specifically,the evolution in gas permeation properties following irradiation over a wide range of doses will be discussed.Ion irradiation resulted in combined increased permeability and permselectivity for several gas pairs of interest.
