Polyethylene (PE)/epoxy blends filled with graphite were prepared and studied in this work. The in-plane and through-plane conductivities of the composites increased from 11.68 Scm⁻¹ to 73.11 Scm⁻¹ and 0.20 Scm⁻¹ to 4.12 Scm⁻¹, respectively, as graphite content increased from 30 to 80 wt%. Phase bonding effect of the compatibilizer and reinforcing effect of the filler enhanced the flexural modulus and strength of the composites up to 70 wt% filler content. The electrical conductivities attained by these composites being significantly higher than comparable composite formulations in literature show the edge of immiscible PE/epoxy blend for achieving high-conductivity polymer composites.

制备并研究了填充有石墨的聚乙烯（PE）/环氧共混物。面内和贯通面电导率的复合材料从11.68增加SCM ^-1至73.11 SCM ^-1和0.20 SCM ^-1至4.12 SCM ^-1分别作为石墨含量从30增加至80重量％。相容剂的相结合作用和填料的增强作用提高了复合材料的挠曲模量和强度，最高可达70 wt％的填料含量。这些复合材料获得的电导率显着高于文献中的可比复合材料配方，显示出不混溶的PE /环氧共混物的优势，可实现高电导率的聚合物复合材料。
