In this study, nonwoven superhydrophobic fibrous polyvinylidene fluoride (PVDF) membranes of nearly uniform thickness were produced via electrospinning PVDF solution with a mixture solvent of N,N-dimethylformamide (DMF)/acetone. In order to improve and stabilize the membrane performance in the water-oil separation process, the structures and properties of resultant membranes were optimized by controlling a series of factors including polymer dope compositions and spinning parameters. Surface contact angle measurements confirm that all the electrospun PVDF membranes exhibit a rougher surface with high hydrophobicity. The obtained electrospun PVDF nanofiber membranes showed excellent performance in separation of water-oil emulsions. |
