润湿性是植物叶片的一个重要界面特性。它用来描述当粘合剂接触到树叶表面时发生的事情。表面自由能是一个重要的参数，可以用来估算液滴与植物叶片之间的结合功(结合强度)。采用座滴法测定了烷基糖苷(APG)在黄瓜叶片上的静态接触角。在此基础上，利用数学模型计算了黄瓜叶片的固体表面自由能。在此基础上，用Zisman方法估算了黄瓜叶片的表面自由能。固定法测定不同叶片的表面自由能结果与接触角法测定的结果基本一致，证明了该方法对不同类型叶片的适用性。
Wettability is an important interface characteristic of plant leaves. It is used to describe what happened when an adhesive contacted with a leaf surface. The surface free energy is an important parameter that can be used to estimate the cohesion work (cohesive strength) between the liquid drop and plant leaves. In this paper, the sessile drop method was employed in this study to measure the static contact angel of Alkyl Polyglucoside (APG) on cucumber leaves. On basis of which, the solid surface free energy of cucumber leaves was calculated by the mathematic model. From these measurements, the surface free energy of cucumber leaves was estimated by the Zisman method, too. The surface free energy results of the sessile method for the different leaves were similar to the results measured by contact angle method, giving credence to applicability of this method for evaluating different types of leaves.
