Researchers synthesized the waterborne soya alkyd (WSA), in which soya oil monoglyceride was used as a precursor, and its RGO dispersed nanocomposites (WSA-RGO) via ex-situ polymerization using solvent-less green approach. The synergistic effect of nano-fillers and poly melamine co-formaldehyde isobutylated solution modified organic matrix (WSA) on physico-mechanical and corrosion inhibition of these coatings on finally polished carbon steel (CS) was investigated.

The results revealed that the nanocomposite coatings exhibit promising corrosion protection performance which is evident from the icorr, Ecorr, impedance and phase angle values of coatings (i.e. icorr 7.736×10-9 Acm-2, Ecorr -0.191 V, impedance ~107 Ω cm2 and phase angle 86o). These results suggest that the proposed waterborne nanocomposite coatings exhibit superior corrosion protection property than those of other such earlier reported systems.
