Abstract

Inspired by biological systems, self-healing materials were achieved by incorporating microcapsules into matrix. Urea-formaldehyde microcapsules filled with EPA were prepared by in situ polymerization method. Surface morphology, size distribution, chemical structure, and thermal analysis of microcapsules were analyzed. Self-healing composites were prepared by adding microcapsules to epoxy resin. Results show that healing efficiency was dependent on the microcapsule concentration. Fracture toughness could be fully restored when the microcapsule concentration was 10%. Finally, microcapsules can be raptured by crack and solvents were release to crack region confirmed by SEM.
