In this study, emulsion electrospray was used to store the repair agent inside the mesocapsules. The self-healing coating was made by placing the core-shell mesocapsules with restorative and curing agents on the epoxy coating. The shell used in the structure of the mesocapsules was poly (co-acrylonitrile). Examination of mesocapsules made using Scanning Electron Microscopy revealed that mesocapsules were produced under optimum conditions of electrospray with favorable morphology and size. The mean diameter of these mesocapsules for epoxy core and curing agent was 870 and 776 nm, respectively. Examination of the structure of mesocapsules produced by transmission electron microscopy for both types of core in the core confirmed the core-shell structure. Fourier Transform spectroscopy results confirmed the physical appearance of the shell with two types of cores side by side and no chemical reaction between the shell and the core. Thermal core results also confirmed the presence of two components in the produced mesocapsules. Thermal degradation results of core-shell mesocapsules showed that thermal degradation of core-shell mesocapsules with curing agent and curing agent is something between the degradation of each component that this type of thermal degradation behavior is a reason for successful encapsulation of the core into the crust. Mechanical tests of adhesion, flexural strength and gloss were used to investigate the effect of adding mesocapsules on the mechanical properties of the coating. The results of the adhesion test showed that by adding mesocapsules at higher percentages, the adhesion of the coating was reduced compared to the control coating. However, the adhesion of 1% by weight of mesocapsules will decrease by 17%. Also, flexural strength test results showed that addition of mesocapsules would decrease the bending percentage of coatings and decreased 21% in 1% by weight of mesocapsules. The gloss test results showed a decrease in gloss due to the addition of mesocapsules due to surface roughness. Corrosion evaluation was performed qualitatively by salt fog test. Prevention of corrosion of metal substrate and self-healing of coatings was determined in 1 wt% sample and corrosion was observed in higher percentages of mesocapsules. The self-healing evaluation was performed quantitatively using the Tafel and EIS tests, and the self-healing efficiency for the coatings was calculated, with the self-healing coefficient of coverage containing 99 wt% of the core-shell mesocapsules equal to 99% and the diagrams for each the tests showed the superiority of 1% by weight of mesocapsules over 5 and 10% coatings.
