Surface Science deals with studies of the physics and chemistry of surfaces. The term surface is defined as all interfaces between solids, polymers, biomaterials, nanostructures, soft matter, liquids, and gases. Surface science is closely related to interface and colloid science. The Langmuir adsorption equation is used to model monolayer adsorption.
The study of surfaces and interfaces is essential for a better understanding of the way in which solid materials and liquids interact. Tensiometers enable the precise characterisation of contact angles and surface tensions providing valuable information on the interactions at a solid-liquid or liquid-liquid interface. These interactions play a key role in adhesion, wettability, biocompatibility and adsorption properties.

This attraction is termed surface tension and can be measured with optical, force and bubble tensiometers. A liquid-liquid phase boundary is referred to as interfacial tension and can be measured with force and optical tensiometers.
Interaction between a liquid and solid can be attractive or repulsive. When attracted by the solid, the liquid spreads, forming short drops with low contact angles. If repelled, the drops are taller, rounder and have high contact angles.
Surface free energy is surface tension for solids, the higher the surface free energy the easier it is to wet a substrate. Surface free energy of solids can be measured via contact angle measurements with a range of liquids
