    摘要： 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. Furthermore, the supercritical fluid infusion process aids to improve the toughness of the composite films significantly regardless of the existence of metal.

    摘要： Disclosed are methods and systems for dispersing nanoparticles into a matrix. Disclosed is a system and method for coating a carrier film with a resin, spraying the resin with a suspended nanoparticle solution, and then transferring the resin-nanoparticle matrix to a collection vessel for dispensing for end use. Also, suspended nanoparticle solution is sprayed onto carrier film, the film is dried, a fabric layer is coated with resin layer, and nanoparticles are then transferred into the fabric resin layer to create a nanoparticle-infused fabric matrix. Fabric layers can also be coated with resin and sprayed with nanoparticles. Also disclosed is a system and method for coating a first carrier film with nanoparticles, coating a second carrier film with resin, and transferring nanoparticles from first carrier into the resin layer on the second carrier to create a nanoparticle infused resin material that can be collected and dispensed for end use.
