To solve defects existing in polyethersulfone (PES) coatings and improve their performance, polytetrafluoroethylene (PTFE) and functionalized graphene (fG) are incorporated into PES coatings to develop a new PES‐PTFE/fG coating. The incorporation vastly improves the anticorrosion properties of the coatings due to the synergistic effect of PTFE's low surface energy and fG's “labyrinth effect” and their filling effects. Moreover, results of research on the effects of different adding proportions of PTFE and fG on coatings properties show that PES‐PTFE/fG 1 exhibits the lowest water absorption and still possesses high anticorrosion properties after long‐term corrosion tests, suggesting that it has optimal anticorrosion properties. © 2019 Wiley Periodicals, Inc.
