- •
An LbL approach for the deposition of GO on a hollow fiber support was explored.
- •
GO nanosheets could effectively cover the surface defects and narrow pore size.
- •
Fabricating GO/Torlon® composite membrane could save polymer consumption.
- •
High heavy metal removal efficiency and long-term stability were achieved.
