A novel kind of miniature boat that might have many potential applications was fabricated from superhydrophobic copper meshes for the first time. These boats not only floated freely on a water surface but also exhibited striking loading capacities. By selection of the pore size of copper meshes, a loading capacity greater than 11.0 g could be readily achieved for a boat of 8.0 cm(3) in volume. The large loading capacity is believed to arise from the air film surrounding the superhydrophobic surfaces of boats. The results of this study present new applications of artificial superhydrophobic surfaces in areas of miniature aquatic devices.
首次采用超疏水铜网制备出一种可能具有多种潜在应用的新型微型船。这些船不仅可以在水面上自由漂浮，而且还表现出惊人的承载能力。通过选择铜网的孔径，可以轻松地为 8.0cm(3)体积的船实现超过 11.0g 的承载能力。大承载能力据信源于船的超疏水表面周围的气膜。本研究结果为微型水上装置领域的人工超疏水表面提供了新的应用。
