To reduce energy consumption and broaden the scope of application of polyethersulfone/polytetrafluoroethylene (PES/PTFE) coatings, three hybrids have been designed by incorporating PES/PTFE coatings with different contents (0, 10, and 20?wt %) of crosslinking agent consisting of epoxy resin and appropriate curing agent (ER‐CA) in the application as low‐temperature curing PES/PTFE coatings and named as EP‐0, EP‐1, and EP‐2, respectively. The addition of ER‐CA gives rise to satisfactory distribution of PTFE, making PTFE play its roles better and improves barrier properties of the coatings by secondary leveling and its own crosslinking structure, which greatly enhances anticorrosion properties. Compared with EP‐0 and EP‐2, EP‐1 exhibits lower water permeability. Even after long‐term exposure to corrosive environments, EP‐1 still possesses high anticorrosion properties.
