Abstract
(EN)
A method for manufacturing semi-conductive polypropylene resin foamed particles of the present invention comprises the steps of: allowing carbon nanotubes to be adsorbed on surfaces of polypropylene resin composition pellets to manufacture carbon nanotube-adsorbed pellets (CNT-PP); and foaming the carbon nanotube-adsorbed pellets (CNT-PP) to form foamed particles.
