Multifaceted incorporation of epoxy/functionalized maize cob nanoparticle with biosynthesis silver nanoparticles for composite coating of mild steel

The distribution of nanoparticles in the production of epoxy coating results in particle clustering and agglomeration. In this work, biosynthesis of silver nanoparticles was used to modify maize cob ash nanoparticles to avoid particle clusters. The stir-air spray method was to developed composite coating of 0, 2, 4, 6, 8, and 10 wt% nano-maize cob ash modified with 0.5 wt% AgNPs. The microstructure, adhesion strength, wear, and thermal behavior of the coating were investigated. Optimal properties were obtained at 0.5 wt% silver nanoparticles modified with 8 wt% nano-maize cob ash with 84.26% thermal properties, higher wear resistance, a lower coefficient of friction with deep cuts, less plastic deformation, and fewer wear grooves. It is established that low-cost biosynthesis of silver nanoparticles can be used to improve the distribution of nano-maize cob ash for the polymer coating of mild steel.
