Triboelectrification surface interactions

When a particle becomes charged by triboelectrification, two types of interactions may contribute to the deposition and adhesion of the particle, namely electrical double layers and Coulombic interactions. Electrical double layers are considered to result from the formation of a shell of oppositely charged electrical layers at the interface upon contact. Coulombic interactions result from the forces of interaction which arise between charged particles and uncharged surfaces.
