Preparation and characterization of superhydrophilic PVDF electrospun nanofibrous membrane based on in situ free radical polymerization

Superhydrophilic and ultrafine polyvinylidene fluoride (PVDF) electrospun nanofibrous membranes (ENMs) were successfully fabricated by electrospinning based on an in situ free radical polymerization. The properties of electrospinning solution were investigated, as well as the morphologies and hydrop...

Description
Summary:Superhydrophilic and ultrafine polyvinylidene fluoride (PVDF) electrospun nanofibrous membranes (ENMs) were successfully fabricated by electrospinning based on an in situ free radical polymerization. The properties of electrospinning solution were investigated, as well as the morphologies and hydrophilicity of ENMs. The results showed that PVDF ENMs with in situ free radical polymerization had high porosities and rough surfaces endowing their surfaces superhydrophilicities. The water contact angle reduced from 135° to 0° within 0.2s. •Superhydrophilic and ultrafine PVDF nanofibers were successfully fabricated.•The obtained fibers had high porosities and roughness surfaces.•The obtained fibers also had high pure water flux.
