Abstract

Starch is an eco-friendly polymer for various applications, from medical applications to optoelectronic once due to its biocompatibility. Polymer nanocomposites based on starch, zinc oxide nanoparticles (ZnO NPs) and graphene oxide (GO) are synthesized using a casting technique. Optical properties were studied by a UV-vis spectrophotometer, and the nanocomposite molecular structure was determined using a Fourier transform infrared (FTIR) spectrometer. The starch absorption edge was shifted to the region of lower energy. It was found that starch has two absorption edges and hence two optical band gaps. The direct and indirect optical band gap values were determined for pure starch, starch/ZnO and starch/GO nanocomposites. The incorporation of 6wt.% of ZnO NPs reduces the indirect optical band gap from 4.77 to 2.88 eV. Meanwhile, the incorporation of 2wt.% of GO reduced the band gap to 2.15 eV.
