Abstract Amphiphobic surfaces are attracting increasing attention because of their extensive applications in self-cleaning surface, water/oil separation, anti-corrosion coating, etc. Nevertheless, the development of amphiphobic surfaces is notoriously difficult, usually requiring both surface microstructure construction and surface energy modification. In order to avoid surface energy modification with expensive and harmful fluorine-containing compounds, a mushroom structure array was formed by sputtering using a target material of silver (Ag) in this study. Without any chemical modification, the developed mushroom structure presented the desired surface amphiphobicity, highly repellent to various solutions with different surface tensions. In particular, a flexible polymer substrate was applied considering the potential popularization of deformable electronic devices in the near future. It was simple to achieve the desired deformable electrode materials via the deposition of Ag film on the flexible polymer substrate. The coating presented good mechanical robustness against the repeated fatigue test, with a minimal change in the electrical resistance after 10000 bending cycles. The superior performances in surface wettability and mechanical test promised the developed materials to be extensively applied as deformable electrode materials with waterproof and anti-fingerprint surfaces in practice.

在柔性聚合物基底上制备蘑菇状结构的双疏导电涂层

摘要 两性表面因其在自清洁表面、水油分离、防腐涂层等方面的广泛应用而受到越来越多的关注。然而，众所周知，两性表面的开发非常困难，通常需要表面微结构构建和表面能修改。为了避免使用昂贵且有害的含氟化合物进行表面能改性，本研究中使用银 (Ag) 靶材通过溅射形成蘑菇结构阵列。在没有任何化学修饰的情况下，开发的蘑菇结构呈现出所需的表面两性，对具有不同表面张力的各种溶液具有高度排斥性。特别是，考虑到在不久的将来可变形电子设备的潜在普及，应用了柔性聚合物基板。通过在柔性聚合物基板上沉积银膜来获得所需的可变形电极材料很简单。该涂层在反复疲劳试验中表现出良好的机械强度，在 10000 次弯曲循环后电阻变化最小。其在表面润湿性和力学测试方面的优异性能保证了所开发的材料在实践中作为具有防水和防指纹表面的可变形电极材料得到广泛应用。该涂层在反复疲劳试验中表现出良好的机械强度，在 10000 次弯曲循环后电阻变化最小。在表面润湿性和力学测试方面的优异性能保证了所开发的材料在实践中作为具有防水和防指纹表面的可变形电极材料得到广泛应用。该涂层在反复疲劳试验中表现出良好的机械强度，在 10000 次弯曲循环后电阻变化最小。在表面润湿性和力学测试方面的优异性能保证了所开发的材料在实践中作为具有防水和防指纹表面的可变形电极材料得到广泛应用。
