Charged Interfaces

Abstract

Interfaces form at the physical boundary between two phases, such as between a solid and a liquid (S/L), a liquid and its vapor (L/V), or a solid and a vapor (S/V). There can also be interfaces between two different solids (S1/S2) or between two immiscible liquids (L1/L2). This chapter will consider two special interfaces, the solution/air interface and the metal/solution interface. A brief discussion of the solution/air interface is useful in pointing out some general properties of interfaces. The metal/solution interface is, of course, of paramount interest to the study of corrosion.
