AbstractHollow mesoporous silica microspheres (HMSN) were selected as carriers for storing 2-aminino-5-mercato-1,3,4-thiadizole (ATM) in this experiment. The synthesised microspheres were uniformly dispersed, with a diameter of approximately 500 nm, as identified by scanning electron microscopy. HMSN, as excellent nanocarriers, were used to encapsulate ATM with a 19 wt% loading rate. Then, 18 wt% HMSN loaded with ATM was added to the coating. Electrochemical impedance spectroscopy and scanning Kelvin probes were used to investigate the self -healing ability of the coating with ATM encapsulated in hollow mesoporous silica microspheres. The copper corrosion caused by microdefects in the coating was delayed by controlling the slow release of ATM from the microspheres. The active corrosion resistance of the coatings was strengthened. By optimising the coating, the service life of the coating can be extended to achieve the long-term corrosion protection of copper.
