Double-layer capacitors energy requirement

Deryaguin s theory essentially treats the adhesive/substrate system as a capacitor which is charged due to the contact of the two different materials. Separation of the parts of the capacitor, as during interface rupture, leads to a separation of charge and to a potential difference which increases until a discharge occurs. Adhesion is presumed to be due to the existence of these attractive forces across the electrical double layer and the energy, Ac, that is required to separate the interface is given as ...
