A novel silver / activated - polyvinylidene fluoride - polydimethyl siloxane hydrophilic-hydrophobic Janus membrane for vacuum membrane distillation and its anti-oil-fouling ability

In the membrane distillation process, the anti-fouling ability of the membranes is one of the main factors that affect the use of the membranes. In this paper, the Silver/Polyvinylidene fluoride - Polydimethyl siloxane (Ag/PVDF-PDMS) hydrophilic-hydrophobic Janus composite membrane was prepared by chemical reduction method to construct the underwater oleophobic silver layer on the surface of the hydrophobic Polyvinylidene fluoride - Polydimethyl...
