Article Synopsis
- The research focuses on enhancing the water stability and antibacterial properties of polyvinyl alcohol (PVA) membranes, which are limited for biomedical uses.
- By using zirconium-based metal-organic frameworks (UiO-66-NH) and applying heat treatment, a new composite membrane (UiO-66-NH@PVA NFMs) is created that improves the mechanical support and hydrophilicity of PVA.
- The study shows that these modified membranes can effectively deliver the antibacterial drug levofloxacin, achieving over 99.9% bacteria reduction against E. coli and Staphylococcus aureus, making them promising candidates for improving wound healing in clinical settings.
Except the good separation performance, the membranes used for oil-water mixture separation should be fabricated with as little wastewater produced as possible. Thus, we proposed a green tactic--water vapor induced phase inversion to prepare the high-strength and superhydrophilic/underwater superoleophobic nonwoven fabric-based cotton/PA6/PAN membranes which is based on the polymer/solvent/nonsolvent ternary system analysis. Differing from adding additives in polymer solution or coagulation bath, above proposed strategy has an "subtractive effect" with the advantages of constructing three-dimensional porous structure and greatly reducing the organic wastewater produced during preparation process.
