Abstract：

The membrane used in air separation and oxygen enrichment is an important class of gas separation membranes. In this study, silicone rubber/polysulfone (PDMS/PS) composite membranes were prepared; the silicone rubbers included solvent-based hydroxyl silicon rubber and emulsion hydroxyl silicon rubber. The prepared composite membranes were evaluated by the permeation rate and separation factor. The results showed that the permeation rate of solvent-based silicon rubber/polysulfone membrane was 3-4 times more than that of emulsion silicon rubber/polysulfone membrane, but the latter had a little better separation factor than the former. The oxygen permeation rate Q(O2) and separation factor α (O2 N2) was 113 GPU and 2.00, respectively. This latex coating method, coating emulsion hydroxyl silicon rubber on the support, was not only environment-friendly, but also safe and economic.
