Abstract Honeycomb-like silver nanowires (AgNWs) aerogel is constructed via a convenient ice template method and further thermally welded, followed by backfilling with polydimethylsiloxane (PDMS) to obtain AgNWs/PMDS elastomer. A high electromagnetic interference (EMI) shielding effectiveness (SE) of 74.7 dB (8.2 GHz) can be achieved in the elastomer with a low AgNWs content of 3.08 wt% and a thin thickness of 1 mm owing to welding and well-aligned pores structure of AgNWs skeleton. Also, the shielding performance of the elastomer displays negligible change after 1000 bending and stretching cycles. These traits underscore the great potential of the AgNWs/PMDS elastomer in today’s flexible electronics.

热焊接蜂窝状银纳米线气凝胶回填聚二甲基硅氧烷用于电磁干扰屏蔽

摘要 蜂窝状银纳米线 (AgNWs) 气凝胶通过方便的冰模板法构建并进一步热焊接，然后用聚二甲基硅氧烷 (PDMS) 回填以获得 AgNWs/PMDS 弹性体。由于焊接和对齐良好的孔结构，在具有 3.08 wt% 的低 AgNWs 含量和 1 mm 的薄厚度的弹性体中可以实现 74.7 dB (8.2 GHz) 的高电磁干扰 (EMI) 屏蔽效率 (SE) AgNWs 骨架。此外，弹性体的屏蔽性能在 1000 次弯曲和拉伸循环后显示出可以忽略不计的变化。这些特性强调了 AgNWs/PMDS 弹性体在当今柔性电子产品中的巨大潜力。
