Magnetite doped cuprous oxide nanoparticles as modifier for epoxy organic coating

In this paper, a novel in-situ preparation method of multipurpose additives based on Cu2O·2Fe3O4 nanocomposite is presented. Cu2O·2Fe3O4 nanocomposites were synthesized in large quantities by a simple and facile one-step co-precipitation method in the presence of poly(ionic liquid). The prepared Cu2O·2Fe3O4 nanomaterials were applied as multipurpose epoxy coating additive to improve its coating performances as marine coatings of steel. The nanocomposites were characterized by FTIR, XRD, SEM, TEM, and DLS techniques. The incorporation of poly (ionic liquid) into Cu2O·2Fe3O4 nanocomposites reduced the particle size, increased the porosity and zeta potential, leading to improve of the adsorption sites and affinity toward interaction with epoxy coatings. The Cu2O·2Fe3O4 nanocomposites improved the adhesion strength, mechanical stability and self-healing characteristic and the flame retardancy with decreasing the total smoke production of epoxy coatings with steel.
