摘要
接触角是最方便、应用最广泛的表征固体表面的标准方法之一。简单介绍了固液接触的基本理论以及接触角各种主要的测量方法,包括躺滴和悬泡接触角测量方法、Wilhelmy吊片法等,进而通过实验叙述了水银与固体电介质表面接触角的测量步骤等。
Contact angle is one of the handiest and most widely used methods, which are used to identify solid surface. This paper simply introduces basic theory of solid-liquid contact and several main contact angle-measuring methods, among whom there are sessile drop and pendent bubble, Wilhelmy method. etc., and describes the measuring procedures of the contact angle between mercury and solid dielectric by using an experiment.
