To investigate the effects of graphene (Gra) modified by 1-hexadecyl-3-methylimidazolium bromide (IL) on the crystallization kinetics behaviour of PVDF, a series of PVDF/IL blend, PVDF/Gra and PVDF/IL/Gra nanocomposites were prepared.

Based on the selective adsorption property of the imidazolium-type hyperbranched polymeric ionic liquid (hb-PIm+PF6-) towards anionic dyes, it was incorporated into poly(vinylidene fluoride) (PVDF) matrix to modify PVDF film. The composite hb-PIm+PF6-/PVDF films were prepared via non-solvent-induced phase inversion method. The obtained composite films were characterized by attenuated total reflectance-Fourier transform infrared spectroscopy, scanning electron microscopy, and contact angle goniometry. Using bromophenol blue (BPB, an acidic dye) as the model molecule, the dynamic and static adsorption properties of the hb-PIm+PF6-/PVDF films were investigated, respectively. It is significant that the hb-PIm+PF6-/PVDF composite films could efficiently remove BPB from water under dynamic condition.
