摘要: In situ polymerization of aniline monomers in the presence multiwall carbon nanotubes (MWCNTs) leads to core–shell nanostructures for use conductive polymer composites. The conductivity nanofibers can be tuned by altering coating thickness. These high-aspect-ratio MWCNT-polyaniline are dispersed polystyrene (PS) using solution mixing. composites exhibit electrical percolation at a much lower concentration than MWCNT/PS Polyaniline (PANi), when used as layer, is able attenuate electromagnetic (EM) waves via absorption. dielectric measurements MWCNT-PANi/PS show one order magnitude increase real permittivity compared with that composites, making them suitable charge storage purposes.
