Radiation Induced Grafting

A conductive polymer, polyaniline (PANI) has been grafted onto a poly (vinylidene fluoride) (PVDF) based polymer using simultaneous radiation induced grafting (RIG), which is a new approached in introducing the conductive properties into a preformed polymer for potential selective separation ability during filtration process. The possibility of coating PVDF membrane with PANI was investigated by looking at the effect of monomer concentration, radiation dose, and aniline in emulsion form on the degree of grafting (DOG). The DOG were obtained at 4.44 and 5.43 % for aniline concentration and its emulsion respectively, and increases with the increase in concentration. The PANI-grafted-PVDF membrane was also characterized using Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy/energy dispersive x-ray spectroscopy (SEM/EDX) and differential scanning calorimetry (DSC) techniques. The FTIR and SEM results show that PANI was successfully grafted onto PVDF membrane. EDX analysis also confirmed the grafting by the presence of NH2 representing aniline in the PANI-grafted-PVDF membranes. The modification was found to have not change the overall properties of PVDF, still retaining its intrinsic properties.
