Advances in Biomimetic Soft Defect-Resistant Materials
In many man-made materials,strength and toughness are mutually exclusive.The key to endow materials with high strength and high toughness simultaneously is to impart materials with defect resistance via structural design.There are plenty of natural materials which have high strength and high toughness.With unique natural defect-resistant structures,such materials provide rich inspirations for the structure designs of synthetic materials.This work introduces the main mechanisms of defect resistance of materials and reports the recent advances of biomimetic high-performance defect-resistant materials,especially for the soft materials.Inspired by natural defect-resistant prototypes,the related biomimetic materials also show great mechanical properties such as high strength and high toughness,which is benefit for the improvement of the bearing capacity and the operational reliability.Meanwhile,the prospects in this field are briefly described.
