    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.

    Abstract: The present disclosure provides a resin blend containing a blend of a first phthalonitrile resin, a filler, and a bisphenol M diphthalonitrile ether resin. Suitable fillers include at least one of nanoparticles, microparticles, or fibers. The present disclosure also provides an article including a polymerization product of such a resin blend. The resin blends can be prepared at lower temperatures than phthalonitrile resin blends without a bisphenol M diphthalonitrile ether resin.
