PVDF/CaCO3 composite hollow fiber membrane for CO2 absorption in gas-liquid membrane contactor

Porous hydrophobic polyvinylidene fluoride (PVDF) composite hollow fiber membranes were fabricated via phase inversion method by embedding different amounts of hydrophobic calcium carbonate (CaCO3) nano-particles in the polymer matrix. The effects of nano-particle loadings on the morphology, structu...
