Abstract

Thermally resistant and mechanically stable novel hyperbranched waterborne polyurethane-urea/silica hybrid coatings were prepared by using 3-aminopropyltriethoxysilane as a coupling agent with SiO₂ as a crosslinker. The extent of hydrogen bonding was investigated to show a dependence on SiO₂ concentration, which increased the glass transition temperature of the polymers with increasing SiO₂ concentration. Thermal decomposition profiles and the corresponding stability data suggest two-step decomposition for the hybrids; further, their stability increased with increasing concentration of SiO₂.
