An electrospinning method to prepare ionic liquid( IL) incorporated poly( vinylidene fluoride ) ( PVDF ) nanofibers was adopted in this paper. X-ray photoelectron spectrometry ( XPS ) , Fourier transform infrared spectrophotometer ( FTIR ) and X-ray diffraction( XRD ) results showed that the IL which appeared on the surface of the nanofibers was miscible with PVDF, and also led to a higher content of beta-phase crystal in PVDF. The IL content in the nanofibers exerted a significant impact on the surface morphology and wettability of the composite nanofibers, and thus the freezing time, crystallization temperatures of water droplets on these surfaces as well as ice adhesion strength. The results showed that the PVDF nanofibers with 10% IL presented both the highest water repellency and the best anti-icing property.
