| 題目：Learning from Nature: Biological and Bio-inspired Materials 主講人：陳柏宇助理教授 (國立清華大學 材料科學工程系) 時間：102年12月18日(星期三13:30-15:30) 地點：三峽校區文學院文1F11教室 摘要: Most biological (natural) materials are sophisticated composites whose mechanical properties are often outstanding, considering the weak constituents from which they are assembled. These biological composites, which have risen from hundreds of million years of evolution, are inspiring scientists and engineers in the design of novel materials. Their defining characteristics, self assembly, structural hierarchy, multi-functionality, and self-healing capability, will be presented with selected biological materials investigated in our group: abalone shells, crab exoskeletons, bird beaks/feathers, fish scales/teeth, deer antlers, and armadillo armor. Attachment devices used in nature, e.g. gecko foot, tree frog toe pads, and abalone foot, will be reviewed. The Materials Science and Engineering approach is applied by correlating the structure with mechanical properties at varying hierarchical length scales. Finally, several novel approaches to synthesize bio-inspired/bio-mimetic composites will be discussed. |
