Charge transport, adsorption and percolation transitions on electrified surface

In the present work the surface discharge of electrets is considered. Particular attention is given to the phenomena of adsorption and nucleation of electrically conducting phase in the course of percolation charge transport on the electrified surface. The basis for consideration is formed by the percolation model of charge relaxation in electrets originally proposed in 1984. This model is founded on the simultaneous use of percolation theory and Kolmogorov conception for 2D nucleation kinetics. Such an approach has allowed to get a quantitative description for charge decay on the electrified surface under the action of electrically conducting external agent, primarily, the ambient air humidity
