Metallized nanotube polymer composite (MNPC) and methods for making same

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 matrix, superstrong nanotubes (NT), nanoparticle inclusions. MNPC is prepared by supercritical fluid infusion metal precursors (Au, Pt, Fe, Ni salts), incorporated simultaneously or sequentially, into solid NT-polymer composite followed thermal reduction. The infused precursor tends diffuse toward the surface preferentially as well surfaces reduced form nanometer-scale particles coatings. conductivity increases with metallization, provides better shielding capabilities against EMEs radiations reflecting absorbing EM waves more efficiently. Furthermore, process aids improve toughness films significantly regardless existence metal.
