文摘
- •
Asymmetric PVDF membrane incorporated with graphene was prepared using the NIPS method.
- •
Graphene worked as nuclei for PVDF crystallization and transformed PVDF from γ-form to α-form.
- •
Hydrophobicity of the membrane substrate interface increased after graphene incorporation.
- •
Hybrid membranes have better CO2 absorption performance with stronger wetting resistance.
- •
Membrane orientation affected the CO2 absorption in membrane contactor.
