| Sumario: | [EN] The influence of injection molding parameters on electrical properties and morphology of PC/ABS-MWCNT nanocomposites is presented in this article. Investigation is based on the masterbatch of 5.0wt% carbon nanotubes obtained by melt-mixing. Further processing includes dilution of this nanocomposite to desired concentrations on twin-screw extruder and injection molding or direct dilution of masterbatch in injection molding. Additionally, reprocessing of materials formed by compression and injection molding is presented along with the change in electrical conductivity. Morphology differs strongly between the two processing paths showing change in agglomeration behavior between nanotubes concentrations. Electrical properties show dependence on injection velocity and melt temperature in both applied processing paths. Moreover, electrical conductivity recovery is proved after injection and compression molding. |
