Triboelectric nanogenerators (TENG) is of great interest as an emerging power harvester due to its simple device architecture and high efficiency. Despite development of various surface modification techniques for enhancing the performance of a TENG with a given triboelectric pair of materials, a method capable of being used universally on a variety of surfaces and improving the performance of TENGs with diverse surfaces remains a challenge. Here, we demonstrate a novel transfer-printing technique of hierarchically dewetted polymer droplets on various TENG surfaces for performance enhancement of the TENGs. Our method is based on controlled dewetting of a thin supramolecular assembled film of two end-functionalized polymer blends on a prepatterned poly(dimethyl siloxane) mold, followed by the physical pattern-transfer of arrays of the dewetted droplets consisting of supramolecular assembled nanostructures on a TENG contact surface. The hierarchically dewetted microdroplets comprising soft-etched nanopores efficiently improve the performance of a TENG by more than three times compared to one without the transferred pattern. The pattern-transfer is successfully achieved on various surfaces including not only oxides, plastics, rubbers, and metals, but also fabrics, coins, vegetables, and shells, making our approach a convenient way for enhancing the triboelectric performance of a given TENG.

摩擦电纳米发电机（TENG）由于其简单的设备架构和高效率而作为新兴的能量收集器受到了极大的关注。尽管已经开发出各种表面改性技术来增强给定的摩擦电材料对的TENG的性能，但是一种能够在各种表面上普遍使用并改善具有各种表面的TENG的性能的方法仍然是一个挑战。在这里，我们展示了一种新型的转移印刷技术，用于在各种TENG表面上分层去湿润的聚合物液滴，以增强TENG的性能。我们的方法是基于在预先形成图案的聚（二甲基硅氧烷）模具上对两个末端官能化的聚合物共混物的超分子组装薄膜进行控制的去湿，接下来是在TENG接触表面上由超分子组装的纳米结构组成的去湿液滴阵列的物理图案转移。与没有转印图案的TENG相比，包含软蚀刻的纳米孔的分层润湿的微滴有效地提高了TENG的性能三倍以上。图案转移不仅在氧化物，塑料，橡胶和金属，而且在织物，硬币，蔬菜和贝壳等各种表面上均能成功实现，这使我们的方法成为增强给定TENG摩擦电性能的便捷方法。与没有转印图案的TENG相比，包含软蚀刻的纳米孔的分层润湿的微滴有效地提高了TENG的性能三倍以上。图案转移不仅在氧化物，塑料，橡胶和金属，而且在织物，硬币，蔬菜和贝壳等各种表面上均能成功实现，这使我们的方法成为增强给定TENG摩擦电性能的便捷方法。与没有转印图案的TENG相比，包含软蚀刻的纳米孔的分层润湿的微滴有效地提高了TENG的性能三倍以上。图案转移不仅在氧化物，塑料，橡胶和金属，而且在织物，硬币，蔬菜和贝壳等各种表面上均能成功实现，这使我们的方法成为增强给定TENG摩擦电性能的便捷方法。
