壁虎的动态吸附与壁虎纳米材料仿生学

以壁虎为代表的一类脚底板具有超细绒毛结构的动物具备极强的吸附和脱附能力。这种独特的能力引起科学家的极大关注并逐渐成为研究的热点。与一般的粘附材料（比如胶水）产生的吸附力不同的是，这种吸附力可以在需要时产生或消失（动态吸附）。模拟这种结构的纳米材料具有极高的实用价值。本文以壁虎为例，从化学、物理学、生物学、机械工程学及材料学的角度全方位系统地介绍了壁虎动态吸附理论和基于这种理论在仿生方面研究的最新进展，最终提出本领域研究工作的展望。

Dynamic Adsorption of Gecko and Bionics of Gecko-Like Nanomaterials

Some animals such as the gecko have the hairlike plantar structures. They have very strong attaching and dettaching ability which is increasingly attracting scientists’ attention and becomes the hot point in scientific research. The adhesive force produced by the gecko is different from others produced by the commom bonds like the gluewater. It can appear or disappear when needed(dynamic adsorption). A huge potential application is prospected for producing several gecko-liked materials or apparatuses. In this paper, the dynamic adsorption of gecko and the new research results of nano-bionic materials based on this theory in chemistry, physics, biology and materials science are introduced with the prospects in this field proposed.
