        摘要：The development of membranes for gas separation was reviewed.Several types of membranes for gas separation were introduced, including drying technique of reverse osmosis membrane in 1970’s, "resistance model" and "composite model" membranes in 1980’s, and integrally skinned asymmetric membranes in 1990’s.The membrane-forming mechanism by microphase separation phenomena during an quench step of an initially thermodynamically stable polymer solution was emphatieally analysed.And finally the shortcomings of present membrane-forming technique were preposed and the development trend was given.

        摘要：Porphyrins and their metallic complexes have many particular properties, and they have been widely used as models of cytochrome P-450, oxidation catalysts, chemical electrodes and special functional materials etc..When supported with SiO2 or montmorillonite or organic polymers, the porphyrins or their metallic complexes are compartmentalized, and exhibit better oxidation resistance.This paper reviews the new developments of synthesis and properties of polymer-supported porphyrins and their metallic complexes, especially as models of cytochrome P-450, photobactericidal materials, anion carriers, sensitization and electron transfer materials and so on.
