Conductive nanocomposite coatings—manufacturing, features, and technical revolution

In this review, conducting nanocomposite coatings have been discussed for corrosion protection of metal substrates and alloys. Conducting polymers reveal inherent corrosion protection properties, which were further enhanced by adding nanoparticles to form efficient nanocomposite coatings. In this regard, conducting coatings filled with carbon nanoparticles (carbon nanotubes, graphene, graphene oxide, etc.) have good corrosion resistance, durability, mechanical properties, wear resistance, adhesion, and barrier properties for metal substrates. Several methods have been used for manufacturing of nanocomposite coatings such as solution method, spray technique, dip coating, spin coating, electrodeposition, chemical vapor deposition, etc. Conducting polymer nanocomposites have been applied for technical applications such as electronics, energy devices, solar cells, and engineering materials.
