Inspired by the idea of deriving morph‐genetic materials from natural templates, the indicalamus leaf is used as a template in an electroplating method designed to prepare a zinc surface with a hierarchical microstructure similar to that of the indicalamus leaf. The leaf templates are first sintered at high temperature under vacuum to leave the carbon skeleton of indicalamus leaf behind; a layer of zinc is then plated directly onto this surface. The zinc coating inherits both the nanoscale slice structures and micrometer‐scale mastoid structures of the leaf. This hierarchical structure confers the hydrophobicity of the leaf onto the zinc coating. The resulting surface exhibits super‐hydrophobicity with low adhesion and a contact angle as high as 167°. The influence of various current densities on the hydrophobic properties of the fabricated zinc surfaces is studied, and the optimal parameters for the preparation of the super‐hydrophobic zinc surface are determined.

电镀制备自靛蓝叶继承的具有分层结构的超疏水锌涂层

受自然模板衍生形态发生材料的想法启发，靛蓝叶被用作电镀方法的模板，该电镀方法旨在制备锌表面，其微观结构类似于靛蓝叶。首先将叶片模板在真空下进行高温烧结，以留下靛蓝叶片的碳骨架。然后将一层锌直接镀在该表面上。锌涂层既继承了叶片的纳米级切片结构又具有微米级的乳突结构。这种分层结构赋予了叶片在锌涂层上的疏水性。产生的表面表现出超疏水性，低附着力和高达167°的接触角。
