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 26):
The precursor to a polyurethane/urea nanocomposite according to any of  claims 18 - 25  wherein the surface modified silicon carbide nanoparticle additionally comprises a second surface modification group derived from a second surface modifying agent, wherein the second surface modification group is covalently bound to the surface of the silicon carbide core and not covalently bound to any polyol, and wherein the second surface modification group is a moiety according to Formula IIb: wherein each open valence of the silicon atom of the second surface modification group is bound to a hydroxyl group (\u2014OH) or is covalently bound to the surface of the silicon carbide core through an oxygen atom, chosen independently for each open valence; and wherein R 4  is selected from aliphatic or aromatic groups having a molecular weight of between 13 and 350 which are unbranched, branched or cyclic, and which are optionally substituted and optionally contain heteroatoms.
