Chromatebased coatings are widely used as corrosion preventive surface treatment. The use of Cr6+ in home appliances and automotive parts has already been prohibited in Europe due to its carcinogenicity, mutagenicity and teratology. The increasing needs for high-performance Cr6+-free coatings demand development of new systems with active corrosion protection.
Functionalised layered double hydroxide (LDH)/carbon nanotube (CNT) additives will be incorporated into hybrid (POSS) based coatings. The expected impacts are:
- improved products at acceptable costs with respect to current existing technologies
- reduced usage of hazardous materials
- sustainability of developed technology throughout the entire products life cycle.
The environmentally-friendly products will bring significant economic benefits to the transport industry (automotive, aerospace) and building industry without harmful impacts on both the environment and the society.
