文摘
- •
Fiber membranes with nanoporous structures were obtained via thermal-nonsolvent induced phase separation.
- •
PLLA nanoporous fiber membranes were prepared by electrospinning a single solvent system.
- •
A water bath was used to obtain the PLLA nanoporous fiber membranes regardless of humidity.
- •
This kind of PLLA nanoporous fiber membranes possessed high specific surface area and water flux.
- •
The nanopore structures endow membranes excellent performance in oil adsorption and organic dye filtration.
