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), H 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.
在酸性条件下，以硝酸铈铵（CAN）为引发剂，通过二极管激光将聚苯胺（PANI）接枝到阿拉伯胶（GA）上。通过改变二极管激光功率、辐照时间、PANI、CAN、GA 的浓度、反应时间和温度，优化接枝条件，以获得最高的接枝产率百分比（90%）和接枝效率百分比（36%）。傅里叶变换红外光谱（FTIR）、H 核磁共振（NMR）、X 射线衍射（XRD）、热重分析（TGA）和扫描电子显微镜（SEM）技术用于表征所制备的接枝共聚物 GA-g-PANI，它可用作药物输送载体来控制脑部的癌症。本研究重点关注该领域的新趋势和最新发展，发现二极管激光是一种高效、清洁的合成 GA-g-PANI 的方法。
