- Abstract
Two-phase polymer blends consisting of a polypropylene matrix and dispersed polycarbonate particles containing multi-walled carbon nanotubes (MWCNTs) have been injection molded. The obtained plastic moldings were patterned by laser treatment. The initially non-conductive molded plastic parts became electrically conductive in the treated areas after the laser treatment. Structures with line resistances of as low as 1.5 kO/cm-1 were created on the surface of the parts. The dependency of the reachable resistance values on the parameters of the laser treatment, the material composition (the mass fraction of MWCNT in the polymer blend 3wt%...5wt%) as well as the injection molding parameters were investigated.
