文摘
- •
PVDF-CTFE membrane was prepared by NIPS for MD desalination.
- •
Different types of LiCl-based mixed additives were used as pore-forming agent.
- •
Effect of PEG/LiCl mass ratio was investigated centered on phase inversion process.
- •
PEG/LiCl with even content was the optimal mixed additives for PVDF-CTFE membrane.
- •
Mixed additives was affirm for enhancement of membrane performance.
- •
Membrane with high performance was gained mainly from the interconnected structure.
