Performance In order to obtain a microcapsule self-healing coating with outstanding wear and corrosion resistance, a novel double-walled microcapsule filled epoxy resin (EP) coating was fabricated by assembling graphene oxide (GO) onto the outer shell layer of polysulfone (PSF) through polydopamine (PDA) modification. The surface of the as-prepared double-walled microcapsules was rough with a particle size of 60-70 ?m and a wall thickness of 2-3 ?m. With enhanced dispersion and compatibility, the double-walled microcapsule filling composite coating showed enhanced mechanical performance and thermal stability.
