MULTI-LEVEL PROTECTION OF MATERIALS FOR VEHICLES BY 'SMART' NANOCONTAINERS -MUST

摘要

This paper describes briefly the concept of the FP7 Project "MUST" aiming at development of next generation of protective coatings for transport industry. The main vision of the project is to develop new coating technologies based on active multi-level protective systems for future vehicle materials in automotive, aerospace and marine industry. This particular paper reviews part of the work where automotive applications are particularly concerned. The main objective of the project covers design, development, testing and application of novel multi-level protection systems as coated materials for future vehicles radically improving long-term performance of metallic substrates. On the other hand metallic or hybrid joints bonded by adhesives containing intelligent release systems are expected to show improved durability and protection against corrosive disbonding. The multi-level protection is established by the novel self-healing concepts employing various active mechanisms. New self-healing coatings and adhesives will be based on "smart" release nanocontainers incorporated in commercial paints, lacquers and adhesive formulations. A multi-level self-healing approach will combine - in one same system - several damage prevention and reparation mechanisms, which will be activated in response to environmental conditions. The perspectives, challenges and limitations of application of the self-healing coatings and adhesives in the future car designs will be discussed in the present paper.
