Abstract

In this paper, polypropylene (PP) and ethylene-octene copolymer elastomers (POE) were used as the matrix resin, and carbon black (CB) and graphene (GNP) were added as conductive fillers. An X-ray diffractometer was used to compare the crystal structure of CB and GNP, and the dispersion of conductive fillers in the materials were observed by scanning electron microscopy. The relationship between the electrical conductivity of the composite material and the temperature was explored. The effect of graphene on the conductive performance of the shielding material was evaluated. The results show that the addition of GNP can improve the conductivity of the shielding material at a lower content of conductive fillers; however, at a higher content of conductive fillers, the improvement of the conductivity of the shielding material is insignificant.
