A Versatile Coating Approach to Fabricate Superwetting Membranes for Separation of Water-in-Oil Emulsions
is important because of the frequent occurrence of oil spill accidents. Utilizing superwetting porous membrane has become a promising approach to separate either surfactant-free or surfactant-stabilized emulsions. Herein we report a facile and versatile strategy for preparing hydrophobic/under-oil superhydrophobic membranes by coating the skeletons of the membranes with the poly[(3
3
3-trifluoropropyl)methylsiloxane] (PTFPMS) nanoparticles. The obtained membranes could be used to separate various water-in-oil emulsions with high flux and separation efficiency. In addition
owning to the outstanding resistance of PTFPMS to the most organic solvents or oils
the modified membranes exhibited the excellent reusability and the antifouling properties that were critical in the practical applications. Many commercially available membranes can be modified by such a simple method.
