Abstract (en)

[origin: WO2012069760A1] The present invention relates to the field of hydrophobic solid surfaces, and more particularly to polyvinylidene fluoride (PVDF) membranes having a superhydrophobic surface. The invention also relates to the process for preparing these membranes and also to the industrial applications thereof. The PVDF membranes according to the invention comprise a superhydrophobic surface comprising a structure that is porous on the nanometre scale and interconnected crystalline nodules of micrometre size.
