Polyvinylidene fluoride PVDF powder was chosen as the base material, and grafted with styrene monomer under pre-irradiation graft polymerization method. The styrene grafted PVDF (PVDF-g-PS) powder was characterized by FTIR spectroscopy, DSC, TGA and element analysis. The FTIR spectra demonstrate that the polystyrene is successfully grafted into PVDF powder. The crystallinity of grafted PVDF powder decreases with the increasing in the degree of grafting according to the DSC curves. The TGA curves of PVDF-g-PS change remarkably with respect to the original PVDF. It further proves the polystyrene is successfully grafted into PVDF powder.
