Development of green anticorrosion coatings for steel protection based on environmentally friendly nanoparticles and conducting polymers

Objective

The overall objective of the STEELCOAT project is to reduce the use of toxic and hazardous compounds in, and extend the service life of, anticorrosion coatings for steel. The project aims to develop novel green, environmentally friendly, anticorrosion coatings with extended durability for steel protection. We will develop both high solids (HS) solvent-borne and water-borne anticorrosion maintenance coatings. The corrosion protection in these novel coatings will be achieved by combining green nanoparticles, conductive polymers and binders.

Steel is an excellent material with high strength and outstanding mechanical properties and it has been used for centuries. Exposing bare steel surfaces to a corrosive environment will lead to corrosion of the steel surfaces and thus pose a potential danger to the whole steel structure, reducing its service life. The cost of corrosion is 3-4 % of GDP worldwide and is therefore a very important issue for all modern societies. Many compounds that are used in the corrosion protection of steel today are hazardous to the environment and to human health. For example, hexavalent chromium has been used in inhibitive pigments but these pigments are being phased out due to environmental and health concerns. Thus, there is an urgent need to replace current paint systems with new effective systems that are more environmental friendly and not hazardous to human health.

In the STEELCOAT project we will develop new HS solvent-borne and water-borne anticorrosion maintenance coating systems for steel protection through the combination of nanoceria, nanoclay, conductive polymers and binders. In order to optimize the corrosion protection of the novel systems we will devote a part of the project to increased fundamental understanding of the mechanisms of corrosion protection. Furthermore, in the development of the coating formulations we will investigate and optimize the mechanical properties of the coating and the adhesion to the steel surface.
