Abstract. The main purpose for this study is to investigate the effect of ZnO and ZnO/carbon with different aspect ratio of celluloses on the conductivity performance, surface morphologies and also to produce the appropriate film for light-emitting diode (LED) applications. The experiment will be divided into three main phases which is synthesis of the ZnO Cellulose and ZnO/carbon Cellulose, characterization of the nanocomposite and producing the thin films as a product. In these study the different aspect ratio of cellulose 0:100, 2:98, 4:96, 6:94, 8:92, 10:90 was used as a matrix during the samples preparation for Zinc Oxide (ZnO) and ZnO/carbon to synthesis ZnO Cellulose and ZnO/carbon cellulose. The morphology of ZnO and ZnO/carbon has been set to nanorods by controlling the potential of hydrogen (ph) during chemical deposition methods. The nanorods ZnO reinforced cellulose indicate the excellent conductivity performance. Moreover, with the increase of the aspect ratio were likely to form a 3D network structure with higher concentration of pores, increase in physical properties, chemical properties furthermore, it’s significantly improved conductivity of the nanocomposite compared to the simple cellulose and Zinc Oxide films. Based on X-ray diffraction, and scanning electron microscopy characterization proved the existence of Cellulose and ZnO in the nanocomposites films. UV-Vis spectrometry has been used to identify the optical properties for the ZnO and ZnO/carbon with the different aspect ratio of cellulose. The absorption band showed a shift compared to the normal absorption band, this is all due to strong interaction between ZnO crystal and cellulose surface. ZnO/carbon cellulose is a composition between electrical, optical and material properties which makes it a flexible material, valuable and also has a high demand in the manufacture of electronic devices.
