Preparation of composite reverse osmosis membranes by plasma polymerization of organic compounds. III. Plasma polymers of acetylene/CO/H2O

摘要

AbstractReverse osmosis characteristics of composite membranes prepared by the plasma polymerization of acetylene/CO/H2O mixtures with various ratios of components are investigated; porous film of cellulose nitrate‐cellulose acetate is used as the substrate. This monomer system seems to have the following advantages: (1) A relatively short deposition time (1–2 min) is enough to produce reasonably good reverse osmosis membranes; and (2) good chemical stability of membranes can be obtained, especially in the case of chlorine resista
