内容摘要：

Self-healing polymers and polymercomposites represents a class of materials with built-in capability ofrehabilitating damages. Damages that are inevitably generated in materialsduring fabrication and service can be automatically repaired on a microscopicscale and would no longer develop into macroscopic failure as in the case ofconventional materials. The topic has attracted more and more attention in the pastfew years. The on-going research activities clearly indicate that self-healingpolymeric materials turn out to be a typical multi-disciplinary area. Thepresent report briefly reviews the works carried out in the authors’ laboratorytowards strength recovery for structural applications.

The self-healingmethodologies developed to date can be classified as intrinsic and extrinsicaccording to the method used for delivering the healing components to thetarget site in the material. Unlike intrinsic self-healing that operates as aresult of inter- or intra-macromolecular interactions in the absence ofadditional healing agents, extrinsic self-healing involves the embedment of ahealing agent. Extrinsic self-healing can be more easily realized incommercially available polymers because no structural modification of thematrix molecules is required.
