Carbon nanotube-reinforced siloxane-PMMA hybrid coatings with high corrosion resistance

► Organic-inorganic hybrid-carbon nanotubes nanocomposite coatings on carbon steel. ► High dispersion of multiwall carbon nanotubes in the siloxane-PMMA matrix. ► Relation between bonding structure and corrosion protection efficiency. ► High thermal stability and excellent anticorrosion performance in acidic environment. ► Environmentally compliant protection of metal surfaces.
