The Research on the Electrical Properties Change in Extrusion Molding of Resin Matrix Multi-Walled Carbon Nano Tubes Composites

Abstract:

Prepare poly butylene terephthalate (PBT)/multi-walled carbon nanotubes (MWNTs) composites through the method of melt blending. Then use low-cost single screw extruder to conduct experimental research and analysis on the extrusion test sample of PBT/MWNTs composites of different proportions under the conditions of changing the extrusion temperature, rate, cooling mode and so on. As a result, the process parameters of the better extrusion temperature, critical extrusion rate, and high-gloss molding etc. to reinforce the electrical properties of composites under low-cost experiment condition have been obtained. The experiment results also indicate that with the increasing of the MWNTs content, the surface resistivity of the composites shows a declining trend.
