Institute of Applied Chemistry, Academia Sinica

The present statatus of the development of oxygen enrichment process using gas separating polymeric membranes for intensified combustion process of fossil fuels for energy saving as well as for medical use is discussed. Most important directions in recent researches for more efficient oxygen enriching membranes are reviewed,including:effect of chemical structure of polymer molecules on its permeative properties,effect of addi-tion of small molecules and liquid crystals,permeative properties of segmented and graft multiphase polymers,and formation of ultrathin membrane on a porous substrate by in situ polymerization or plasma polymerization.
