Preparation of polydimethylsiloxane-SiO2/PVDF-HFP mixed matrix membrane of enhanced wetting resistance for membrane gas absorption

Membrane gas absorption (MGA) has been widely used to separate CO2 from gas mixture attributed to its high interfacial area. In order to secure high absorption flux, the pores of the membrane need to be non-wetted. Currently, hydrophobic membrane suffers from severe pore wetting over prolonged periods of operation. This has called for the enhancement of membrane hydrophobicity to suppress the tendency of pore wetting. In this work, highly...
