摘要
通过实验筛选出典型的几种具有疏水性、防粘性(以竹叶为代表)的植物叶片,用电子显微技术对叶表形态进行了SEM电镜扫描,并借助仪器对叶表面的水滴接触角进行测定,分析结果表明:植物叶片非光滑表面结构、表面附属物、表面材料的质地不同,对其疏水性、防粘性均有不同的影响。叶表面非光滑且附蜡粒的形态,其疏水性强,反之则弱。本研究将为工程仿生制造与设计提供宝贵的信息源。
Several typical hydrophobic anti-stickness plant leaves were selected by experiments (major one is bamboo leaf). SEM scanning was carried out on leaf surface morphology with electromicroscopic technology, moisture engage angel of leaf surface was determined as well. Analytical results shows that, variety of texture of non-smooth plant leaf surface structure and surface material have different influences on hydrophobicity and anti-stickness. Hydrophobicity of nonsmooth surface morphology adhered to wax granule is strong while the opposite one is weak. The study also provides valuable information for the development of bionics engineering.
