Main Measurement Principles/Applications:
Contact angle measuring instruments primarily analyze the surface profiles of liquid and solid samples through optical projection.
The contact angle refers to the angle θ formed at the intersection of the gas, liquid, and solid phases. This angle is currently the best method for determining the wettability of a material surface.
Surface tension refers to the pulling force between any two adjacent parts of a surface, perpendicular to their unit length boundary line.
Interfacial tension refers to the force generated between a liquid and another immiscible liquid.
Surface energy refers to the force between molecules on the surface of an object.
Adhesion work refers to the work required to separate two condensed phases due to the interaction forces between their molecules.
