文摘
- •
Novel organic–inorganic TFC NFMs are fabricated via a mussel-inspired strategy.
- •
The inorganic ZrO2 selective layer is ultrathin, defect-free and uniform.
- •
Organic–inorganic TFC NFMs show excellent water flux along with high rejection.
- •
PDA-PEI coating enhances the structure stability of organic–inorganic TFC NFMs.
