Hydrophilic

Hydrophilic

Hydrophilic literally means water-loving, which means that a substance interacts strongly with water (or other polar substances). When talking about hydrophilic surfaces, they are always covered by a mostly invisible water film. Most metals are hydrophilic, as are glass surfaces. Hydrophilic surfaces have contact angles to water close to 0°.

Implantat vor und nach der Plasmabehandlung

Implant before plasma treatment hydrophobic (left) and hydrophilic after plasma treatment (right)

The opposite of hydrophilic is hydrophobic. The aim of plasma treatment is often to convert hydrophobic surfaces into a hydrophilic state, as then adhesives, lacquers etc. adhere better and an increase in quality can be achieved.
