HYDROPHOBICITY ENHANCEMENT OF PVDF-HFP MEMBRANE INDUCED BY POLYDIMETHYLSILOXANE-GRAFTED-SILICA NANOPARTICLES FOR MEMBRANE GAS ABSORPTION

Membrane gas absorption (MGA) is a promising technology for carbon dioxide removal from flue gas stream to reduce global warming. Membrane acts as the non-selective barrier between the mix gas and liquid absorbent by allowing the diffusion of CO2 via pressure difference. For stable operation, the po...
