几十亿年的进化历程使得自然界生物体某些部位巧夺天工,具有特殊性质,给人研究仿生材料得到启迪。例如甲壳虫可以将糖及蛋白质转化成为质轻然而强度很高的坚硬外壳;蜘蛛吐出的水溶蛋白质在常温下竟变成不可溶的丝.而丝的强度却比防弹背心材料还要坚韧;鲍鱼(石决明)以及人们通常认为用途不大、极简单的物质如海水中的白垩(碳化钙)结晶形成的贝 The billions of years of evolution have led to the discovery of some parts of nature’s biological bodies, which have special characteristics and inspired the study of bionic materials. Beetles, for example, convert sugar and protein into a light, high-strength, hard shell. Spatter’s water-soluble proteins become insoluble filaments at ambient temperatures, while the strength of silk is tougher than bullet-proof vests. Abalone Stone Caiming) and people generally think that use is not very simple substance such as seawater in the chalk (calcium carbide) crystallization of shellfish
