This paper proposes dual-functional sheets (DFSs) that simultaneously have high thermal conductivity (TC) and electromagnetic interference (EMI) absorbing properties, making them suitable for use in mobile electronics. By adopting a simple but highly efficient dry process for manufacturing core-shell structured fillers (CSSFs) and formulating a close-packed filler composition, the DFSs show high performance, TC of 5.1 W m\u003csup\u003e-1\u003c/sup\u003e K\u003csup\u003e-1\u003c/sup\u003e, and a -4 dB inter-decoupling ratio (IDR) at a 1 GHz frequency.

本文提出了同时具有高热导率( TC )和电磁干扰( EMI )吸收性能的双功能片( DFSs ),使其适合在移动电子中使用。通过采用简单而高效的干法制备核壳结构填料( CSSFs ),并制定密排填料组成,DFSs在1 GHz频率下表现出高性能,TC为5.1 W m-1 K-1,IDR为-4 dB。特别是DFSs具有3 k V mm-1的高介电击穿电压( BDV ),有利于在大多数电子器件中应用。DFS由两种CSSF组成,它们按照紧密堆积规则、Horsfield的堆积模型和聚二甲基硅氧烷( PDMS )聚合物混合。核心材料为不同尺寸的软磁Fe - 12.5 % Cr和Fe - 6.5 % Si合金粉末,壳层材料为直径1 - μ m的Al2O3陶瓷粉末。DFS的高性能源于其厚而稳定的壳层结构和密排结构的最大填充能力。
