Electrical phenomena that occur at the interface between two different phases. There are five possible cases: gas/liquid, gas/solid, liquid/liquid, liquid/solid, and solid/solid. There are interfacial electrostatic phenomena such as surface potential, contact electricity, piezoelectricity, and triboelectricity, and interfacial electrokinetic phenomena such as electroosmosis and electrophoresis. These phenomena are important for understanding interface chemistry as well as the complex structure of interfaces.

2つの異なる相が接している境界面に現れる電気現象。気体/液体,気体/固体,液体/液体,液体/固体,固体/固体の5つの場合が考えられる。表面ポテンシャル,接触電気,圧電気,摩擦電気などの界面静電気現象と,電気浸透,電気泳動などの界面動電気現象とがある。これらは界面化学とともに界面の複雑な構造を知るうえで重要な現象である。
