Abstract

Application of Hamilton’s method in the calculus of variations to an electrostatic field model of a suspension of charged colloidal particles with selection of a Lagrangian to yield Poisson’s law as the Euler equation has led to the following results: (1) the potential energy of interaction of two parallel plates, representing colloidal particles in suspension, is derived without assuming a specific charge distribution in the domain, (2) the force between the particles is obtained as a result and therefore does not require independent derivation.

In the present theory, no artifact of a charging process to build up electrical double layers in the vicinity of the colloid particles is required. However, the interaction energy is the same as that described by previous investigators.
