PVDF/ MWCNT hollow fiber mixed matrix membranes for gas absorption by Al۲O۳ nanofluid

The study aims to investigate mixed matrix membranes for absorption of CO۲in gas-liquid contacting process by AL۲O۳ nanofluid as liquid absorbent. PVDF/MWCNT hollow fiber mixed matrix membranes were fabricated absorbent and characterized via relevant characterizations. This study showed that the addition of MWCNT to the matrix led macro cavities to be expanded at the cross section of the membrane. According to the results of gas permeation, surface porosity experienced an increasing trend and in contrast surface pore size reduced. By placing the CNTs in porous PVDF, an increase in the surface contact angle and hydrophobicity of the composite membranes was revealed which could be related to the hydrophobic nature of the added nanopaticles as well as increasing the absorbent average surface roughness.
