摘要

Until now,the demand for lighter,stronger,tougher and more wear-resistant materials has remained unmet for diverse applications,as many structural materials prepared by traditional engineering manufacturing techniques seem to be approaching their performance limits [1].Natural biominerals,although composed of relatively brittle minerals such as calcium carbonate and -phosphate or glass and a small amount of ductile biopolymers,always achieve excellent mechanical properties due to their hierarchically ordered architectures and sophisticated interfaces.Thus,biomimetic designs using abundant artificial synthetic units under mild conditions are increasingly considered as viable ways to devise new-styh high-performance structural materials that are expected to exceed existing engineering structural materials [2,3].
