Electrostatic-assembly carbon nanotube-implanted copper composite spheres

A unique method for synthesis of multi-walled-carbon-nanotube- (MWCNT-) implanted copper composite spheres is reported. It involves Cu ions combining with functionalized MWCNTs at molecular level and formation of spheres after reduction, nucleation and growth of Cu ions attaching to the surface of MWCNTs. The MWCNT-implanted composite spheres allow MWCNTs to avoid being damaged and effectively bond to the matrix. This unique spherical structure will serve as an excellent candidate as powders for the fabrication of a bulk MWCNT-reinforced composite with high strength and good thermal and electrical conductivity.
