采用炭黑与高密度聚乙烯、低密度聚乙烯以及线性低密度聚乙烯共混，制备了刚性和坚韧导电复合材料。当炭黑含量为2wt%时，复合材料的逾渗阈值较低.将低密度和线性低密度聚乙烯的复合材料的冲击强度被认为是几乎16和26倍，分别比高密度聚乙烯复合材料。另一方面，炭黑填充的高密度聚乙烯的模量是低密度和线性低密度聚乙烯基复合材料的2倍。随着炭黑含量的增加，复合材料的拉伸模量增加，冲击强度下降。
Stiff and tough conductive composites were manufactured using carbon black compounded with high and low density polyethylene, as well as linear low density polyethylene. A low percolation threshold value for the composites was achieved at 2 wt% carbon black. The impact strengths of the composites incorporating low density and linear low density polyethylene were found to be almost 16 and 26 times greater, respectively, than that of high density polyethylene composites. On the other hand, the modulus of high density polyethylene filled with carbon black was 2 times as high as low and linear low density polyethylene-based composites. Tensile modulus increased with the content of carbon black, however the impact strength of the composites decreased.
