  • 摘要: 随着通信网络、无线设备及航空航天的快速发展,电磁波危害日益加剧,因而亟需电磁屏蔽性能更优异的复合材料。本文采用MXene (Ti3C2Tx)、银纳米线(AgNWs)和多壁碳纳米管(MWCNTs)构建了双层的高导电三维(导电率最高为1.4×104 S·m−1)网络电磁屏蔽复合薄膜(Ti3C2Tx MXene基功能复合薄膜)。特别是采取真空辅助抽滤法(VAF)将10 mL AgNWs及15 mL Ti3C2Tx MXene的水溶液吸附于聚偏氟乙烯(PVDF)/MWCNTs复合薄膜之上,制备出的Ti3C2Tx MXene基功能复合薄膜的总电磁干扰屏蔽效能(EMI SET)高达69.0 dB,比商用标准(20 dB)高出245%,其中吸收损耗效能(SEA)占比85.1%。说明Ti3C2Tx MXene基功能复合薄膜主要的电磁损耗机制为吸收损耗,比电磁屏蔽效能(SSE/t)最高可达2719.8 dB/(cm−2·g)。这项工作为新型MXene材料在电磁屏蔽复合材料中的应用提供了结构设计和研究思路。
