玫瑰花花瓣微观结构与水滴黏附性质的关系
摘要： 利用环境扫描电镜(ESEM)分别观察了新鲜、枯萎的玫瑰花花瓣正、反两面的微观形貌，并通过测量样品的表观接触角表征了其浸润性，采用高敏感性微电力学天平测试了样品表面的粘附力，分析了玫瑰花花瓣微观结构与水滴粘附性质的关系.实验结果表明，微米结构主要影响玫瑰花花瓣的超疏水性，而纳米结构则是导致玫瑰花花瓣具有高粘附力的关键原因.

Abstract: Superhydrophobic surface with high adhesive force has attracted great interest in recent years. An intriguing example is the red rose petals, which is famous with its “petal effect” (i.e. the water droplet adhesion effect) and its novel hierarchical micro-/nano- structure. In this article, the surface adhesive effect was characterized by the high-sensitivity microelectromechanical balance system, and the effects of micro- and nanostructure on the adhesive property of rose petals was investigated. The morphology of obverse and reverse surface of fresh and dry rose petals were observed by environmental scanning electron microscope (ESEM), and the wettability was characterized by the apparent contact angle. The experimental results show that surface hydrophobicity can be enhanced by the micro-scaled structure and the high adhesive force is mainly caused by the nano-scaled structure. It is believed that this work will provide us a new avenue to further understand the wettablilty of solid surface, and design novel microfluidic devices in a wide range of applications, such as many localized chemical or biological reactions, traced analysis, and in situ detection.
