Poly(vinylidene fluoride) (PVDF) fibers have been widely investigated in the fields of electronics, filtration, and oil/water separation due to their exceptional piezoelectric/thermoelectric/ferroelectric properties, excellent chemical/thermal high mechanical properties. However, application PVDF micro/nanofibrous membrane these is still limited solvent toxicity fiber preparation process. In this case, we developed an environmentally friendly strategy for producing pure membranes. detail, centrifugally spun precursor PVDF/poly(ethylene oxide) (PEO) was obtained from a composite spinning solution composed emulsion PEO solution. Subsequently, membranes were sintered at temperature decompose obtain membrane. The results indicate that fibrous present nanostripe bumps on surface. height number can be easily controlled by sintering temperature. Owing surface roughness low energy prepared membranes, droplet rejection (above 155°) produced. Moreover, flux (3837 L·m–2·h–1) water-in-oil efficiency (99.42%). This study describes way fabricate apply them oil–water separation.
