摘要：

New preparation strategies for films that exhibit separation of emulsified oil/water mixtures through a simple, practical, and cost-effective method are highly desirable. Herein a poly (vinylidene fluoride) membrane with superhydrophobic and superoleophilic surface had been successfully fabricated via a facile dip-coating process. As-prepared membrane exhibits good stability of wettability and can be applied for oil and water mixture separation. After cycles, the membranes still keep a relatively high flux, which indicates their great potential for practical applications. (c) 2015 Wiley Periodicals, Inc. J. Appl. Polym.
