The results show that the polymer determines the electricity conducting of coal filled polymer composites. The coal filled PP composites is an insulating material, and be independent of coal type, its direct current resistivity is above 10〓Ω·cm. The resistivity drops with the content of coal when using anthracite, but it is also above 10〓Ω·cm, and the surface modification of coal, especially alkylated, resumes the insulance of composites.

X射线衍射测试表明即使在高变质程度下煤中的石墨晶区含量仍较低，煤填充聚合物复合材料电性能主要由基体材料性能决定，通过动电容静电计对煤填充聚丙烯复合材料直流电导性研究表明，煤填充聚丙烯复合材料是绝缘材料，其绝缘电阻在10〓Ω·cm以上，在高含量情况下，仍能保持良好的绝缘性，而与煤种无关。
