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 sp 2 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.
