What Is an Interface and Why Is It Important?


What Is an Interface?
An interface is the boundary between two non-miscible materials. There are interfaces between liquid-solid, liquid-liquid, liquid-gas, solid-solid, and solid-gas – but not gas-gas. An interface between liquid-gas or solid-gas is called a surface.  

Why Are Interfaces Important?
We are surrounded by interfaces and interfacial phenomena in our everyday lives – such as using shampoo or deodorant, preparing meals, washing our clothes and dishes, and wearing contact lenses. Forming a solid-solid interface by joining two materials together with adhesive or glue is something we take for granted – from postage stamps to airplanes. All of these familiar objects have numerous interfaces that are designed and controlled through interfacial science and technology.

A significant proportion of Dow Corning’s product technology relies on our ability to influence the behavior of these interfaces through an extensive range of silicon-based materials (fluids, emulsions, surfactants, compounds, and coatings).
