Abstract

This experimental research aimed to develop a conductive polymer composite (CPC) material for electromechanical devices. The composite was made by incorporating conductive micro carbon derived from rice husks into a Linear Low-Density Polyethylene (LLDPE) polymer matrix using hot compaction. Variations of filler composition were used, with carbon loading of 50%, 45%, and 40%, and mesh sizes of #150, #200, and #250. The experimental results showed that particle size variations did not significantly affect composite density, but higher mesh selection improved filler dispersion within the matrix, resulting in higher electrical conductivity values. The optimal conductivity value of 9.43E-04 S/cm was achieved with a micro-carbon composition of 50% loading. However, decreasing micro carbon loading had a more significant impact on reducing electrical conductivity values.

微碳粒度和分散对低密度聚乙烯-碳复合材料导电性的影响

这项实验研究旨在开发一种用于机电设备的导电聚合物复合材料（CPC）。该复合材料是利用热压实技术将稻壳中提取的导电微碳加入线性低密度聚乙烯（LLDPE）聚合物基体中制成的。使用的填料成分各不相同，碳含量分别为 50%、45% 和 40%，网目尺寸分别为 #150、#200 和 #250。实验结果表明，颗粒大小的变化对复合材料密度的影响不大，但选择更高的网目尺寸可以改善填料在基体中的分散，从而提高导电率值。微碳含量为 50%时，最佳导电值为 9.43E-04 S/cm。然而，降低微碳含量对降低电导率值的影响更为显著。
