New Insights into the Polymer Coating of Mild Steel Using Activated Orange Juice Functionalized Rice Husk Nanoparticles

Abstract

AbstractNovel insights in the development of polymer coating of mild steel using functionalization of rice husk ash nanoparticles by activated orange juice were investigated. For the potentiostat/galvanostat corrosion performance of the coated materials, 5 wt% potassium sulfate (K2SO4(aq), 5 wt% sodium chloride (NaCl(aq), and 1 M sulfuric acid (H2SO4(aq) were used. 78.81, 71.86, and 55.11% corrosion resistance of the samples of K2SO4, H2SO4, and NaCl. It was concluded that orange juice was able to enhance the dispersion of RHnp in the epoxy coating. The presence of citrate ions in the orange juice acts as a stabilizer and reducing agent, which was attributed to the fine grain size and good corrosion resistance of the composite coating. The work has established that rice husk ash nanoparticles by activated orange juice can be used in the development of composites coating mild steel.
