Abstract:

Article Preview

Zinc oxide (ZnO) nanostructures have attracted great attention as a promising functional material with unique properties suitable for applications in UV lasers, light emitting diodes, field emission devices, sensors, field effect transistors, and solar cells. In recent years, there has been a growing interest among the researchers to incorporate metal nanoparticles into polymer matrix. In the present work, the biopolymer chitin was deacetylated using zinc chloride and sodium hydroxide. The formed zinc oxide is blended with chitosan and the final product has been obtained as nano composite. The prepared material was characterized using FTIR spectroscopy with functional groups of amine (-NH2) for chitosan and ZnO stretching vibration. The crystallite size of materials was confirmed by X-ray diffractometry (XRD).The absorbance of chitosan-ZnO nanocomposite was confirmed by UV-vis Spectroscopy. The surface morphology of prepared materials was analysed using scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The above characterization studies was confirmed the presence of chitosan-ZnO nanocomposite.
