Abstract

A bi-layered superhydrophobic membrane includes top and base layers formed from polypropylene. The bi-layered superhydrophobic membrane can have a thickness ranging from about 100 μm to about 1 mm. When subjected to oil-water emulsion separations, the superhydrophobic membrane can achieve an organic solvent flux of 14,000 Lmhwith a 96% water rejection. The bi-layered superhydrophobic membrane can be effectively used for water filtration, providing both selectivity and permeability, while offering an eco-friendly solution for reuse of polypropylene plastic waste.
