Abstract
A self-diagnosis and self-repair intelligent coating based on microfluidic technology and a preparation method thereof are provided. Microcapsules are prepared by combining microfluidic T-junction and interfacial polymerization. The wall material of the microcapsules is made of polyurea, and the core material is made of diagnostic agent, repair agent and photoinitiator. Self-diagnosis and self-repair microcapsules are evenly distributed in the coating with silicone resin as matrix.
