Nanostructured Hybrid NonisocyanatePolyurethane Coatings

摘要

The high-dispersed inorganic phase can be obtained in the polymer matrix. In according thernelaborated method we use cyclocarbonate-, epoxy- and aminoterminated oligomers for creation ofrnnano-structured nonisocyanate polyuretane organic-inorganic hybrids. The amino-terminatedrndendroligomers were elaborated by co- hydrolysis tetraethylortosicilate, tetraethylortotitanate andrndifferent aminosilanes. During curing process the furthest hydrolysis of dendroaminoorganosilanernoligomers creates secondary nano-structured network polymer by creating ultrananopartiles of SiO2 or TiO2. Using as interpenetrating polymer networks principle in production of composite materialsrnprovides a unique possibility to regulate their both micro-and nano-structured properties. Elaboratedrncoatings have improved wear-, thermo- and UV- resistance and adhesion properties.
