摘要水上舞动的水黾、清晨滑落的露珠、荷上跳动的雨滴，随着科学研究领域的扩大，自然界中各种各样的超疏水现象被发现，并引入到科学研究工作中。随着超疏水材料研究工作的不断深入，超疏水材料制备方法越来越多，但各有优缺点。本实验基于荷叶效应【1】提出了一种新的方法：采用遗态法【2】制备超疏水材料，即以荷叶、棕叶为模板，通过浸泡溶液、烧结制备叶片表面结构保留程度极高的Cu/C表面。结果表明，由此获得的表面超疏水性能极佳。该CU/C表面水接触角高达165°，而滚动角小于5°。研究了实验过程中的温度、浓度等条件对表面超疏水性能的影响。

Title    The preparation of metal super-hydrophobic surface based on plant leaf template and the study of hydrophobicity    properties      

Abstract

Water strider is dancing on the water ,Dew of slipped in the  morning,Raindrop is beating on the Lotus leaf，Various Super hydrophobic phenomena are found in the nature with the expansion of the  scientific research field,and introduced to the work of scientific research。With the study of super hydrophobic materials more and more deeply,more and more preparatory method of super hydrophobic materials has been get, and each

of them has its advantages and disadvantages.This experiment based on the lotus effect and puts forward a new method:preparation of super hydrophobic materials by Morph-genetic ; Cu/C surface with high fidelity of the lotus leaf, palm leaf  surface structure is prepared through the solving and sintering .The resulting surface exhibited excellent super hydrophobicity, showing water contact angles (CA) of up to 165° and sliding angles ( SA) of less than 5°.

Keywords:Super hydrophobic   Morph-genetic materials  Lotus effect      Contact angle
