Well-defined poly(vinylidene fluoride) (PVDF) based-dendrimers synthesized by click chemistry: enhanced crystallinity of PVDF and increased hydrophobicity of PVDF films

This study reports the preparation by click chemistry of a novel fluorinated dendrimer bearing PVDF branches and its characterization by several analytical methods including H-1, C-13, P-31 and F-19 NMR, diffusional NMR, SEC, DLS, ATG, DSC and HRTEM. As remarkable properties, this dendritic PVDF displayed crystallinity (HRTEM highlighted crystalline disc-like zones of ca. 5 nm) and a much higher hydrophobicity than both its precursors with the water contact angle (WCA) reaching 108 degrees.
