摘要
高分子材料制造和使用过程中,经常由于内部的微裂纹和局部损伤,而导致性能下降,影响使用寿命。自修复高分子材料模仿生物体损伤愈合的原理,自行发现裂纹并通过一定机理自行愈合,是一种有着广泛应用需求的高分子智能材料,包括含修复剂型和不含修复剂型两类。它的特点在于自动化、精准化。本文旨在结合近年来最新的研究成果,介绍并归纳多种典型的自修复体系,总结各种优化手段,并针对已发展的自修复材料存在的局限性,对其研究前景进行合理的展望。
In the process of manufacture and usage, the mechanical properties of polymeric materials will decrease due to internal micro-cracks or partial injuries, thus shortening the lifetime of the material. By imitating the principles of organism wound healing, the self-healing polymeric materials, which are able to discover and repair cracks automatically, have been developed through different mechanisms. Because of its rapid and precise response to the formation of micro-cracks inside, self-healing polymeric materials have shown great potential as novel smart materials in some severe conditions. The review tries to summarize recent progress in this field, and to introduce a variety of typical self-healing systems along with optimization methods. Rational design on fabrication of self-healing polymeric materials is also outlooked.
