Corrosion coatings Eggshell wastes have attracted interest in the fabrication of anticorrosion coatings due to chemical compositions (high calcite content) and widespread availability. A new study presents the use of chemically and thermally treated eggshell nanoparticles as fillers in a zinc-rich epoxy matrix in corrosion protection of mild steel in sodium chloride solution at an elevated temperature. Three samples of zinc-rich coatings containing "as ball-milled" eggshell, chemically and thermally treated eggshell nanoparticles were fabricated to form zincrich eggshell nanoparticles epoxy (ZENE) coatings. The structural characterisations indicated that chemical and thermal treatment removed the protein materials from eggshell nanoparticles, leading to ...
