• Stable and durable electromagnetic interference (EMI) shielding performance was achieved in harsh environments by applying a thin protective coating of hydrophobic 1H,1H,2H,2H-perfluorooctyltriethoxysilane (POTS) on polypyrrole (PPy)-modified fabrics.

• The damaged POTS layer can be instantaneously self-healed (~ 4 s) for the first time by the microwave heating effect of PPy.

• The self-healing process is repeatable even after severe damages, highlighting the great potential to exploit EMI shielding materials’ instant microwave heating effects to enable robust and durable EMI shielding applications.

近乎瞬时的自愈涂层，实现稳定耐用的电磁干扰屏蔽

• 通过在聚吡咯 (PPy) 改性织物上涂上一层薄薄的疏水性 1 H ,1 H ,2 H ,2 H -全氟辛基三乙氧基硅烷 (POTS) 保护涂层，可在恶劣环境中实现稳定和持久的电磁干扰 (EMI) 屏蔽性能。

• 通过 PPy 的微波加热效应，受损的 POTS 层可以首次瞬间自我修复（~4 s）。

• 即使在严重损坏后，自我修复过程也是可重复的，突出了利用 EMI 屏蔽材料的即时微波加热效应实现稳健耐用的 EMI 屏蔽应用的巨大潜力。
