Improvement of the protective properties of the nanocomposite polypyrrole-Zinc oxide coating on mild steel by adding the dispersant sodium hexametaphosphate

This work reports on the use of the sodium hexametaphosphate (SHMP) surfactant for the dispersion of ZnO nanoparticles in the PPy polymer matrix for the production of the composite PPy-ZnO as an anticorrosive coating on mild steel. The coatings of PPy, PPy-ZnO and PPy-ZnO-SHMP were electrodeposited...
