New Methods of Preparing Multi-Functional Nanocomposite Coatings
Nanostructured coatings based on interpenetrated polymer network of polyurethanes, polyacrylates or epoxide resins and containing nanoparticles of SiO2, TiO2 and other metal oxides introduced into a polymeric matrix was elaborated. Technology of the unique coatings provides control of their micro-and nano-structures. Formulation of a new class of nanocomposite materials is characterized by the absence of contaminants in the polymers technology . The main components of the technology are branched (dendro)-aminosilanes which serve as curing agents for many oligomers. Additional hydrolysis of aminosilane oligomers creates the secondary nano-structured network polymer that improves performance of the compound.
