  • [Display omitted] •PVA coated PVDF nanofibers can be easily prepared by hydrothermal treatment.•The inherent hydrophobicity of PVDF nanofibers can be changed to hydrophilic.•The hydrogen bonding interaction can induce the crystalline conformation of PVDF.•Resultant nanofibers have significant improvement in the tensile strength.•Prepared membranes promise to aid in filtration due to involvement of PVA coating. Nanofibers fabricated from Poly(vinylidene fluoride) (PVDF) possesses potential applications in the field of filtrations, because of their excellent resistance towards harsh chemicals. However, the hydrophobicity restricts its further application. In this work, we focus on optimal parameters for post-electrospun tethering of Poly(vinyl alcohol) (PVA) as superhydrophilic domain onto each individual PVDF nanofibers by exploiting the in situ hydrothermal approach. The results indicated an increase in nanofiber diameters due to coating of PVA and improved surface wettability of PVDF nanofibers. The tensile tests of nanofibers indicated that mechanical properties of PVDF nanofibers could be sharply tuned from rigid to ductile. Furthermore, the studies strongly suggest that in situ hydrothermal treatment of post-electrospun nanofibers can improve the water contact angle and these nanofibers can be used in varied applications (e.g., in water purification systems).
