Electrical, thermal, and mechanical properties of polypropylene/multiwalled carbon nanotube micromoldings

Abstract In this paper, properties of microparts molded from polypropylene/multiwalled carbon nanotubes (PP/CNT) composites were studied in detail. Results indicated that the percolation threshold of PP/CNT microparts shifted to higher filler concentrations when compared with their compression molded counterparts. Morphology observations revealed that the distribution of CNT is not uniform along the flow direction, which can significantly …
