An experimental investigation of the assembly of glass and copolymer particles, of two different sizes, on two different liquid surfaces is presented. The dynamics of assembly, under the influence of an external electric field, is investigated. It is observed that the particles form a ring structure in a gap between the top and bottom electrodes. The main driving force of assembly is the extent of the influence of the lateral dipolar force exerted between the particles. This force of repulsion and attraction between particles depends on their polarizabilities and the intensity of the external force. The assembly of glass particles around the copolymer particles on air-butyloctyl salicylate liquid is more rapid and effective compared with that of air-silicone oil. Assembly of particles, smaller than 10 μm, under the influence of an electric field is also shown.
