Abstract:
Polyurethane/urea nanocomposites, precursors thereof, and methods of their manufacture and use are provided, the nanocomposites comprising: a) a polyurethane/urea polymer matrix, and b) surface modified silicon carbide nanoparticles dispersed within and covalently bound to a polyurethane/urea polymer comprising the polyurethane/urea polymer matrix. In some embodiments, the surface modified silicon carbide nanoparticle comprises a silicon carbide core and a linking group covalently bound to the surface of the silicon carbide core and covalently bound to the polyurethane/urea polymer. In some embodiments, the linking group is a moiety according to Formula where the urethane group of the linking group is covalently bound to the polyurethane/urea polymer; and where each open valence of the silicon atom of the linking group is bound to a hydroxyl group (—OH) or is covalently bound to the surface of the silicon carbide core through an oxygen atom.

Claim (Index 13):
An erosion resistant film comprising a film of the polyurethane/urea nanocomposite according to any of  claims 1 - 12 .
