Abstract

Polymer composites with carbon nanofillers are promising for electromagnetic shielding, with performance influenced by filler geometry, orientation, and temperature. Spherical carbon black enhances scattering, while anisotropic carbon nanotubes (CNTs) exhibit directional wave propagation and polarization. CNT orientation significantly affects the shielding efficiency, with the perpendicular alignment outperforming the parallel alignment. Temperature-dependent CNT polarization further underscores the need for thermal considerations in material design.

优化聚合物复合材料的有效电磁屏蔽:碳填料性能和温度的作用
含碳纳米填料的聚合物复合材料具有良好的电磁屏蔽性能,其性能受填料的几何形状、取向和温度的影响。球形炭黑增强了散射,而各向异性碳纳米管(CNTs)表现出定向波传播和极化。碳纳米管取向对屏蔽效率有显著影响,垂直取向优于平行取向。温度相关的碳纳米管极化进一步强调了在材料设计中考虑热因素的必要性。
