| Abstract: | The microporous hydrophobic PVDF membranes for membrane distillation were prepared by phase-inversion process with LiCl as the additives. The proper processing conditions are: utilizing high molecular weight of PVDF, taking DMF as the solvent, PVDF concentration is 10%, time of volatilization is 0.5-1 min, Lithium Chloride content is 3%-5%. |
