摘要

摘要: 导电聚合物复合材料(CPC)因其耐腐蚀性好、比强度高、成本低和易加工等良好的综合性能，被广泛用于制备电磁屏蔽材料。本文采用简单的刮膜法和热酰亚胺化法制备了综合性能良好的MXene-羧基化碳纳米管(CCNT)/聚酰亚胺(MXene-CCNT/PI)复合薄膜。MXene和CCNT协同作用构筑了良好的导电网络，赋予薄膜高效的电磁屏蔽效能(EMI SE)，当MXene和CCNT含量均为12.5wt%，膜厚度为80 μm时，电导率和EMI SE分别为5.88 S/cm和26.49 dB，电磁屏蔽效能与厚度的比值(EMI SE/t)为331.13 dB/mm。并且在极端恶劣环境下(酸-碱处理、高低温处理和重复弯曲)显示出持久而稳定的EMI SE。与此同时，MXene-CCNT/PI薄膜仍具有53.17 MPa的拉伸强度、优异的热稳定性(＞500 ℃)和阻燃性能。实现了聚合物基电磁屏蔽复合材料的便捷、高效制备，同时兼顾其优异的力学性能和耐热性能。

Abstract: Conductive polymer composites (CPCs) are widely used for the preparation of electromagnetic shielding materials due to their good comprehensive performance such as good corrosion resistance, high specific strength, low cost and easy processing. In this paper, MXene-carboxylated carbon nanotube (CCNT)/polyimide (MXene-CCNT/PI) composite films with good comprehensive performance were prepared by a simple scraping and thermal imidization method. The synergistic action of MXene and CCNT constructed a good conductive network, which gave the films high efficient electromagnetic shielding performance (EMI SE). When the contents of both MXene and CCNT were 12.5wt%, the film thickness was 80 μm, the conductivity was 5.88 S/cm, the EMI SE was 26.49 dB, and the ratio of electromagnetic shielding effectiveness to thickness (EMI SE/t) was 331.13 dB/mm. Moreover, the film showed long-lasting and stable EMI SE under extreme environments (acid-alkali treatment, high and low temperature treatment, and repetitive bending). At the same time, the MXene-CCNT/PI film still have a tensile strength of 53.17 MPa, excellent thermal stability (>500 ℃), and flame retardancy. Convenient and efficient preparation of polymer-based EMI shielding composites is realized, taking into account their excellent mechanical properties and heat resistance.
