Abstract

Acrylonitrile was successfully grafted on polystyrene modified with carbon nanotubes using gamma-irradiation technique. This process was carried out at various gamma doses (0.2-1.5 Mrad). The new grafted polymer (GP) was characterized and its properties were investigated. In this study, it was found that 2 gm of polystyrene, 90% (w/w) acrylonitrile monomer, 2% (w/w) ferrous ammonium sulfate (FAS) catalyst, 1 mg carbon nanotubes powder and 1.25 Mrad gamma dose are the optimum conditions required for the polymerization of GP. The grafted polymer was proved true by fourier transform infrared spectroscopy (FTIR), UV-Visible spectroscopy and XRD. A mechanism is presented to explain the formation of GP modified with carbon nanotubes.
