Abstract
Grafting of polyaniline (PANI) on Gum Arabic (GA) was carried out in the presence of ceric ammonium nitrate (CAN) under acidic conditions by diode laser as initiator. The grafting condition was optimized by varying the diode laser power, exposure time, concentrations of PANI, CAN, GA, reaction time and temperature were carefully optimized to achieve the highest percentage of grafting yield % GY (90%) and percentage of graft efficiency % GE (36%). The Fourier-transform infrared spectroscopy (FTIR), 1H NMR, X-ray Diffraction (XRD), Thermogravimetric Analysis (TGA), and Scanning electron micrographs (SEM) techniques have been used for the characterization of the produced graft copolymer GA-g-PANI, which used as drug delivery carrier to control cancer in brain. This study focused to new trends and latest developments in this area where diode laser was found to be efficient and, clean method for synthesis GA-g-PANI.
