Bisphenol A cyanate ester/polyglycidyl methyacrylate (BADCy/PGMA) microcapsules were successfully fabricated via solvent evaporation technique, herein, BADCy as a core material, synthesized PGMA as a shell material. Optimal BADCy/PGMA microcapsules with dense core-shell structures were implanted in the Bisphenol A epoxy resin (E-51) matrix, to fabricate the corresponding (BADCy/PGMA)/E-51 self-healing composites. Results revealed that the optimal BADCy/PGMA microcapsules presented a spherical shape and rough surface, with mean diameter of 31.5 μm, wall thickness of 2.2 μm. The core material of BADCy still kept its reactivity after being encapsulated by the shell of PGMA. The BADCy/PGMA microcapsules also presented relatively good thermal stability and proper mechanical stability. Moreover, the fabricated (BADCy/PGMA)/E-51 composite with 8 wt% BADCy/PGMA microcapsules possessed relatively good self-healing performance.
