Contact Angle Measurements and Surface Characterization Techniques

Chapter

Abstract

Contact angle measurement has been an indispensable tool for surface characterization and wetting study due to its simplicity and versatility. In this chapter, major measurement techniques for static contact angle, sliding angle, and advancing/receding angle are overviewed. Critical procedural details including sessile-drop dispensing, drop size, drop profile capturing, and analysis are highlighted and discussed. Best practices on measuring sliding and advancing/receding angles are recommended with support of publications from leading researchers. It is our hope that the techniques described within will be used as guidelines for the research community.
