A fluorine-containing silicone resin substituent group,vinyl group, and inorganic framework (SR-FVI) was synthesized through hydrolytic condensation by using vinyltriethoxysilane, 13-fluorooctyltriethoxysilane, tetraethoxysilane, and tetramethyldivinyldisiloxane as monomers. A new cross-linked hybrid membrane (CHM) was prepared with the hydrogen-containing silicone oil (HSO) as a cross-linking agent, polydimethylsiloxane containing vinyl group and the SR-FVI as matrix materials to enhance its membrane-forming ability and permselectivity. The membrane-forming process and the cross-linking reactions between the silicon–hydrogen bond and the vinyl group were carried out simultaneously at room temperature. The effects of the SR-FVI content in the CHMs, pressure difference, and temperature on the oxygen-enriching properties were evaluated and discussed. A good equilibrium between membrane-forming ability and oxygen-enriching properties was attained, for example, oxygen permeability coefficient and ideal separation factor of the CHM with the SR-FVI content of 50 wt% at 20°C and 0.10 MPa were 594 Barrer and 3.50, respectively. Compared to cross-linked PDMS membranes without the SR-FVI, the CHMs show better gas selectivity and similar gas permeability. The oxygen-enriching property is attributed to the fluorine-containing component in the CHM due to its good oxygen solubility. POLYM. ENG.
