    摘要: Polyurethane nanocomposites are provided which include a polyurethane and surface modified silica nanoparticles covalently bound into the polyurethane. High loadings in excess of 30% may be achieved. In some embodiments, the silica nanoparticles are covalently bound to the polyurethane polymer through a linkage derived from a surface-modifying compound comprising a silane functional group and a polyol segment. In some embodiments the polyurethane nanocomposite may be provided as a tape or film. In addition, precursors for a polyurethane nanocomposites are provided comprising: a first polyol and surface modified silica nanoparticles dispersed within the first polyol. In some embodiments, the silica nanoparticles are surface-modified by reaction with a surface-modifying compound comprising a silane functional group and a polyol segment derived from a second polyol, which may be the same or different from the first polyol.
