Influence of mold cavity thickness on electrical, morphological and thermal properties of polypropylene/carbon micromoldings

Abstract In this work, a comparative study on the electrical conductivity ( σ ) and thermal properties of polypropylene (PP)/carbon microparts with different part thickness (namely, 0.85 and 0.50 mm) is reported. Two different types of carbon filler (i.e., CNT and CB) were adopted to study the efficacy of different carbon fillers in improving the σ of PP/carbon microparts. In general, the σ of 0.85 mm thickness microparts were higher than the …
