Preparation and Volume Resistivity of CNT/Polycarbonate Nanocomposites with Different Injection Molding Temperatures

Abstract:

In this work, carbon nanotube/polycarbonate (CNT/PC) nanocomposites containing 1wt% CNT were prepared by a two-step method of twin-screw extruder mixing followed by injection molding at different temperatures. The microstructure, which has strong impact on the electrical properties of the composite, was affected by the injection molding conditions. This work is focused on the effect of injection molding temperature on the volume resistivity of CNT/PC nanocomposites. The microstructure of the composites was investigated by scanning electron microscopy (SEM). It was found that the volume resistivity of CNT/PC nanocomposites was decreased from 10¹³ to 10⁵ Ω·cm with the increasing injection molding temperature.
