摘要
完全轮廓法(ADSA)是一种通过分析液滴/气泡轮廓以计算表面张力和接触角的方法,其结合各种滴形控制装置可以满足不同的应用需求。首先简单介绍了完全轮廓法的测量原理以及悬滴法、捕获气泡法和限制性座滴法等几种典型的滴形控制装置,然后综述了最新的ADSA表面张力计算方法以及它们各自的优缺点。ADSA法相对于膜天平等传统的表面张力测量方法,具有测量自动化程度高,所需要的样本量小,可实现表面张力动态测量等优点,期望未来可广泛应用于肺表面活性剂的表面张力测量、动态吸附过程研究及肺表面活性剂的高保真生物物理模拟。
Axisymmetric Drop Shape Analysis(ADSA)is a technique for measuring surface tension and contact angles according to the shape of drops/bubbles.It can meet different application requirements when it is combined with various drop shape control devices.We first briefly introduces the measurement principle of ADSA and some typical drop shape control devices,such as pendant drop method,captive bubble method,and constrained sessile drop method.Then,the latest calculation methods of surface tension according to ADSA,as well as their advantages and disadvantages,are summarized.Compared with the film balance method and other conventional techniques,ADSA method has numerous advantages,such as high measurement automation,small sample required,and dynamic measurement of surface tension.It is expected to be widely used in the surface tension measurement of pulmonary surfactants,the study of dynamic adsorption process,and the high-fidelity biophysical simulation of pulmonary surfactants in the future.
