Abstract
A kind of silicone-based composite membranes for oxygen enrichment is prepared by combination of different supported membranes, using modified silicone as a coating material. The oxygen and nitrogen separation performances are tested. The optimal membrane is obtained by adding 5% Si-69 modified polycarbonate-silicone rubber. Its nitrogen and oxygen permeation rates are 500 cm3/(m2·24 h·0.1 MPa) and 2 100 cm3/(m2·24 h·0.1 MPa), respectively, with 4.2 of separation factor, which provides scientific basis for their application in medical field.
