•A straightforward strategy to improve the anti-oxidation properties of BP nanosheets was designed and its underlying mechanism was discussed.•The first use of BP nanosheets as the loading material in polymer coating for corrosion protection.•Composite coatings incorporating PBP-Ce(Ш) nanosheets unveil excellent anti-corrosion properties, flame-retardancy, and wear-resistance. Contemporary industrial sectors are experiencing a growing imperative for coatings that exhibit a multitude of functions. In this study, PBP-Ce(Ш) nanosheets, characterized by robust structural stability, were synthesized using a one-pot method and incorporated into waterborne epoxy resin (WEP) to formulate nanocomposite coatings. The findings demonstrate that the coating, containing 0.6 wt.% PBP-Ce(Ш) nanosheets, exhibits superb anti-corrosion, flame-retardant, and wear-resistant properties. Upon 42 days of 3.5% NaCl solution immersion, the fb of the 6-PBTC coating was a mere 3.55 Hz, significantly lower than the 309.51 Hz measured for the pure WEP coating. Furthermore, the Peak heat release rate (PHRR) of the microscale combustion calorimeter (MCC) and the wear rate of the 6-PBTC coating were reduced by 41.63% and 84.65%, respectively, in comparison to the pure WEP coating. This work not only delves into the utilization of BP nanosheets but also presents a viable solution for advancing the development of multifunctional coatings. [Display omitted]
