Abstract
The object of this study is to develop an easy and simple technique to fabricate the coating solution of Vietnam rice hush ash-derived water glass (VRHA-WG) and Vietnam coconut oil (VCO). The coating solution with different mixing ratio of VRHA-WG and VCO such as 1: 5 and 1:10 (v/v) can be coated on copper substrate. After coating, the substrate are heated at 500oC for 2 hours to enhance the adherence of silica layer and substrate. The characterization of the coating layer are studied by Xray Diffaraction (XRD) and Xray Fluorescence (XRF) while the surface morphology of the substrate before and after coating is study be scanning electron microscope (SEM). Electricity resistant of the substrate after coating increase up to 33.33% compare without coating.
