▎ 摘 要
NOVELTY - Microcapsules comprise a core containing self-healing material and graphene oxide, and a polymer shell surrounding the core. USE - The microcapsules are useful as coating agent (claimed). ADVANTAGE - The microcapsules have excellent heat resistance and storage stability. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) producing microcapsules, comprising (a) polymerizing graphene oxide and self-healing material, and (b) polymerizing polymer, emulsifier, urea and formaldehyde to prepare the microcapsule; and (2) coating agent comprising a curable material, and the microcapsule.
