One-Step Fabrication of Superomniphobic Pvdf-HFPSiO2Membrane for Long-Term CO2 Absorption inMembrane Gas Absorption SystemBy Yee Jack Lai Yong Jie, Pei Ching Oh, Loo Thiam Leng Chew
Abstract: Membrane pore wetting is one of the major challenges for membrane gas absorption, especially when low surface tension liquid absorbents such as amine absorbents are utilized. To minimize diffusion resistance across the membrane, maintaining a non-wetted operating mode in membrane gas absorption is crucial. In this study, a superomniphobic polyvinylidene fluoride-cohexafluoropropylene membrane was fabricated by adding silica nanoparticles (SiO2) in an ethanol coagulation bath through non-solvent-induced phase separation. The surface …
