This study proposes a one‐step method for growing superhydrophobic carbon nanothorn arrays (NTAs) directly on various substrates. The fabricated carbon material (named methyl‐substituted graphdiyne (MGDY)) comprises sp and sp² carbons in a conjugated‐backbone form, as well as methyl groups introduced into the framework as hydrophobic‐enhanced functional groups. MGDY NTAs exhibit excellent hydrophobicity (contact angle ≥152°), substantial long‐period hydrophobic durability (the contact angle decreased by only 3.2% over 800 days), and acid/alkali tolerance. Owing to the enhanced durability and specific stability of carbon, a superhydrophobic interface can easily be constructed using MGDY NTAs, which can be applied to achieve successful long‐term metal‐corrosion protection and efficient oil–water separation.

高度耐用的超疏水碳纳米刺阵列的一步制备。

这项研究提出了一种直接在各种基质上生长超疏水碳纳米刺阵列（NTA）的一步方法。制成的碳材料（称为甲基取代的石墨二炔（MGDY））包含以共轭骨架形式存在的sp和sp ²碳，以及作为疏水增强的官能团引入框架的甲基。MGDY NTA具有优异的疏水性（接触角≥152°），相当长的疏水性（在800天内接触角仅下降3.2％）和耐酸/碱性能。由于碳具有更高的耐用性和特定的稳定性，因此可以使用MGDY NTA轻松构建超疏水界面，该界面可用于成功实现长期的金属腐蚀保护和有效的油水分离。
