Contact electrification of dielectric solids

Abstract The main questions of the basic concept dealing with contact electrification of dielectric solids are summarized. Recent results which have a direct bearing on static electrification of polymer solids are reviewed. Differences between equilibrium contact electrification, transient contact electrification, and steady-state contact electrification are discussed. An analog model of the dynamics of charge exchange between metal and polymer is used to illustrate these differences.
