内容摘要:

Self-healing polymers and polymer composites represents a class of materials with built-in capability of rehabilitating damages. Damages that are inevitably generated in materials during fabrication and service can be automatically repaired on a microscopic scale and would no longer develop into macroscopic failure as in the case of conventional materials. The topic has attracted more and more attention in the past few years. The on-going research activities clearly indicate that self-healing polymeric materials turn out to be a typical multi-disciplinary area. The present report briefly reviews the works carried out in the authors’ laboratory towards strength recovery for structural applications.

The self-healing methodologies developed to date can be classified as intrinsic and extrinsic according to the method used for delivering the healing components to the target site in the material. Unlike intrinsic self-healing that operates as a result of inter- or intra-macromolecular interactions in the absence of additional healing agents, extrinsic self-healing involves the embedment of a healing agent. Extrinsic self-healing can be more easily realized in commercially available polymers because no structural modification of the matrix molecules is required.
