Abstract

This study presents the eco-friendly composites coating with advanced properties that are prepared by chitosan (CS)-modified graphene oxide (GO) filled acrylic-based coating. Photo-curable acrylic-based nanocomposite containing different amounts of chitosan-modified graphene oxide (CS–GO) and the effect of CS–GO on the coating morphology, UV-curing, transparency, tribological, antimicrobial, thermal and anticorrosion properties was studied. The curing study confirmed that the CS–GO absorbed photon but did not affect the final conversion of the coatings. The results of corrosion analysis demonstrated that the CS–GO filled nanocomposite coatings have higher corrosion protection ability than that of pure acrylic and GO filled coatings. The antimicrobial properties of CS–GO filled coating showed that the antimicrobial performance enhanced as the concentration of CS–GO increased. The optical transmittance study shows that the coating's film transparency decreased with increasing CS–GO concentration, but all of the nanocomposite coatings have a high visible transmittance. This study attributes the enhanced properties to the dispersion of the chitosan-modified GO, which greatly improved the interfacial strength of CS–GO and polymeric matrix and enhanced corrosion properties.
