Preferred Label : interfacial double-layer;
IUPAC definition : The Coulombic interaction of interfacial charges (e.g. ions) and the magnetic or electrostatic
interaction of interfacial molecules lead to particularly complex interfacial structures.
Complex interfacial profiles that can be approximated by two distinct sub-layers with
different physical properties (e.g. structure and/or nature and/or composition), are
referred to as interfacial double-layers. Examples of such approximated complex profiles
are: the electrical double-layer consisting of a surface charge layer (i.e. a two
dimensional distribution of one type of ions) and a diffuse charge layer (counter-ions
distributed over the space region next to the surface); the approximated profile of
the orientation angle of anisotropic liquid molecules within a 'double-layer' consisting
of a distribution of so-called anchored molecules which are perturbed (strongly bound
and orientated) by the surface, and the adjacent, so-called, transition layer, i.e.
the region where the surface perturbation is damped.;
