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.

Abstract: A wireless communication system including an electrically conductive passive medium capable of simultaneously propagating therealong electromagnetic first and second currents at different respective frequencies F1 and F2, the electrically conductive passive medium including an electrically conductive first passive linear medium portion adjacent an electrically conductive first passive nonlinear medium portion, the first passive nonlinear medium portion capable of generating an intermodulation current based on a nonlinear interaction between the first and second currents, the intermodulation current having a frequency Fi equal to nF1+mF2 and propagating along the first passive nonlinear medium portion, m and n being positive or negative integers; and a first magnetic film disposed proximate an electrically conductive external surface of the first linear medium portion, such that when the first and second currents propagate along the first passive linear medium portion toward the first passive nonlinear medium portion, the magnetic film reduces or prevents the generation of the intermodulation current in the first passive nonlinear medium portion by attenuating at least portions of the first and second currents.

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.
