【摘要】 通过对植物非光滑表面疏水特性的分析,把疏水表面分为4类:超亲水表面、中等亲水表面、中等疏水表面、超疏水表面。从能量平衡的角度论证了超亲水表面、超疏水表面能量传递符合Cassie模型,中等亲水表面、中等疏水表面能量传递符合W enzel模型,并从许多的植物疏水表面中筛选出4种典型的几何非光滑表面原型,分别构建了凸包型、凹坑型、圆锥型、柱型的理想疏水表面的数学模型,这将为工程仿生脱附的疏水表面设计与制造提供理论依据。更多还原

【Abstract】 The hydrophobic surfaces were divided into four kinds by analysing the hydrophobic characteristic of the non-smooth surfaces of plants: super-hydrophilic,mid-hydrophilic,mid-hydrophobic and super-hydrophobic.In the view of energy balance,the energy transfer of the super-hydrophilic and the super-hydrophobic surfaces conform to Cassie model,and the energy transfer of the mid-hydrophilic and mid-hydrophobic surfaces conform to Wenzel model.Four typical non-smooth surface prototypes were selected from many kinds of hydrophobic surfaces of plants,and the mathematical models for four kinds of ideal reticular hydrophobic surfaces(convex hull style,pit style,taper style,pillar style) were established respectively,which will provide the theoretic base for the design and manufacture of the hydrophobic surface in anti-adhesion of the engineering bionics.更多还原
