Zusammenfassung:A novel time‐ and cost‐saving technique to fabricate a CNT composite film was suggested by using poly(acrylonitrile) nanoparticles coated with functionalized carbon nanotubes. Composite films were formed with fCNTs attached to nanoparticles by hot pressing onto PMMA films. The electrical properties (conductivity and electromagnetic interference shielding effectiveness) of the films were investigated. It was observed that CNT/polymer composite films with PAN nanoparticles coated with fCNTs showed good electrical properties because of enhanced dispersity of CNTs in the polymer matrix.
