Modification of Poly(vinylidene Fluoride) by Grafting of Functional Monomer 3-(Trimethoxysilyl)propyl Methacrylate
3-(trimethoxysilyl)propyl methacrylate was grafted into alkali treated poly(vinylidene fluoride) (PVDF) using free radical polymerization. 1H NMR, IR and DSC spectra of the modified polymer showed that double bonds were produced on PVDF and that 3-(trimethoxysilyl)propyl methacrylate was successfully grafted to PVDF. The membranes prepared using the grafted PVDF showed higher flux and better mechanical property than the pure PVDF membranes.
