Feedback active coatings based on incorporated nanocontainers

Development of a new generation of multifunctional coatings, which will possess not only passive functionality but also active and rapid feedback activity in response to changes in the local environment, is a key technology for fabrication of future high-tech products and functional surfaces. These new multifunctional coatings should combine passive components inherited from "classical'' coatings ( barrier layers) and active components, which provide fast responses of the coating properties to changes occurring either in the passive matrix of multifunctional coatings ( e. g., cracks, local pH change) or in the local environment surrounding the coating ( temperature, humidity). The coatings should also have several functionalities ( e. g., antifriction, antifungal, and anticorrosion) exhibiting synergistic effects.
