Electrically conductive fabrics with liquid repellency and corrosive resistance are strongly desirable for wearable displays, biomedical sensors, and so forth. In the present work, highly electrically conductive and healable superamphiphobic cotton fabrics are fabricated by a solution-dipping method that involves (NH)PdCl-catalyzed electroless deposition of Cu and the subsequent deposition of a mixture of fluorinated-decyl polyhedral oligomeric silsesquioxane (F-POSS) and 1 H,1 H,2 H,2 H-perfluorooctyltriethoxysilane (POTS) on cotton fabrics. Because of their superamphiphobicity, the resulting fabrics are self-cleaning and exhibit excellent resistance against corrosive acidic and basic solutions. The as-prepared fabrics have a sheet resistance of ∼0.33 Ω·sq and show excellent electromagnetic interference shielding and electrothermal heating ability. Because of the preserved F-POSS and POTS molecules, the fabrics can conveniently and repeatedly restore the loss of superamphiphobicity by applying a low voltage of 1.0 V or heating the fabrics at 135 °C to facilitate the migration of the preserved F-POSS and POTS to the surface of cotton fabrics. The integration of healable superamphiphobicity into the Cu-coated fabrics generates multiple functional cotton fabrics with excellent conductivity, electromagnetic interference shielding, self-cleaning ability, and significantly enhanced durability.
具有抗液体润湿性和耐腐蚀性的导电织物对于可穿戴显示器、生物医学传感器等领域非常理想。在本工作中，通过一种溶液浸渍法制备了具有高导电性和可修复性的超双疏棉织物，该方法涉及（NH 4 ）PdCl 催化的无电镀铜和随后在棉织物上沉积氟化-癸基多面体低聚倍半硅氧烷（F-POSS）和 1 H,1 H,2 H,2 H-全氟辛基三乙氧基硅烷（POTS）的混合物。由于其超双疏性，所得织物具有自清洁性能，并表现出对腐蚀性酸性和碱性溶液的优异耐腐蚀性。所制备的织物的面电阻约为 0.33 Ω·sq，并表现出优异的电磁干扰屏蔽和电热加热能力。由于保留的 F-POSS 和 POTS 分子，织物可以通过施加 1.0 V 的低电压或在 135 °C 下加热织物方便且重复地恢复超双疏性的损失，从而促进保留的 F-POSS 和 POTS 向棉织物表面的迁移。将可修复的超双疏性集成到镀铜织物中，生成了具有优异导电性、电磁干扰屏蔽、自清洁能力和显著增强的耐用性的多功能棉织物。
