Abstract
The paper describes the application of ultrasonic shear wave measurements for the assessment of hydrophobicity of various surfaces and real-time non-destructive monitoring of the process of aqueous droplet evaporation. This research focuses on the quantification of surface hydrophobicity expressed through aqueous droplet contact angle and the study of the kinetics of droplet evaporation including evaporation modes (pinned and unpinned) and the characterization of watermarks left after drying.
