Abstract

Graphene nanoplatelets (GNPs) and multiwall carbon nanotubes (CNTs)-polypropylene (PP) composite materials for electromagnetic interference (EMI) shielding applications were fabricated as 1 mm thick panels and their properties were studied. Structural and morphologic characterization indicated that the obtained composite materials are not simple physical mixtures of these components but new materials with particular properties, the filler concentration and nature affecting the nanomaterials' structure and their conductivity. In the case of GNPs, their characteristics have a dramatic effect of their functionality, since they can lead to composites with lower conductivity and less effective EMI shielding. Regarding CNTs-PP composite panels, these were found to exhibit excellent EMI attenuation of more than 40 dB, for 10% CNTs concentration. The development of PP-based composite materials with added value and particular functionality (i.e., electrical conductivity and EMI shielding) is highly significant since PP is one of the most used polymers, the best for injection molding, and virtually infinitely recyclable.

摘要

制备了用于电磁干扰（EMI）屏蔽应用的石墨烯纳米片（GNPs）和多壁碳纳米管（CNTs）-聚丙烯（PP）复合材料，制成1毫米厚的面板并研究了其性能。结构和形态表征表明，所获得的复合材料不是这些组分的简单物理混合物，而是具有特定性能的新材料，填料浓度和性质会影响纳米材料的结构及其导电性。就GNPs而言，它们的特性对其功能有显著影响，因为它们会导致复合材料具有较低的导电性和较差的EMI屏蔽效果。对于CNTs-PP复合板，发现当CNTs浓度为10%时，其表现出超过40 dB的优异EMI衰减。开发具有附加值和特定功能（即导电性和EMI屏蔽）的PP基复合材料具有重要意义，因为PP是最常用的聚合物之一，最适合注塑成型，并且几乎可以无限回收利用。
