diffuse layer

in electrochemistry
Also contains definition of: Gouy layer in electrochemistry
The region in which non-specifically adsorbed ions are accumulated and distributed by the contrasting action of the electric field and thermal motion. Counter and @C01141@ in immediate contact with the surface are said to be located in the @S06003@. Ions farther away from the surface form the diffuse layer or Gouy layer.
