  • Patent number: 9550907
    Abstract: A method for preparing a “preblend” of nano-structured carbon, such as nanotubes, fullerenes, or graphene, and a particulate solid, such as carbon black, graphitic particles or glassy carbon involving wet-mixing and followed by optional drying to remove the liquid medium. The preblend may be in the form of a core-shell powder material with the nano-structured carbon as the shell on the particulate solid core. The preblend may provide particularly improved dispersion of single-wall nanotubes in ethylene-?-olefin elastomer compositions, resulting in improved reinforcement from the nanotubes. The improved elastomer compositions may show simultaneous improvement in both modulus and in elongation at break. The elastomer compositions may be formed into useful rubber articles.

  • Patent number: 9550870
    Abstract: A novel method to develop highly conductive functional materials which can effectively shield various electromagnetic effects (EMEs) and harmful radiations. Metallized nanotube polymer composites (MNPC) are composed of a lightweight polymer matrix, superstrong nanotubes (NT), and functional nanoparticle inclusions. MNPC is prepared by supercritical fluid infusion of various metal precursors (Au, Pt, Fe, and Ni salts), incorporated simultaneously or sequentially, into a solid NT-polymer composite followed by thermal reduction. The infused metal precursor tends to diffuse toward the nanotube surface preferentially as well as the surfaces of the NT-polymer matrix, and is reduced to form nanometer-scale metal particles or metal coatings. The conductivity of the MNPC increases with the metallization, which provides better shielding capabilities against various EMEs and radiations by reflecting and absorbing EM waves more efficiently.
