Evaluation of the forces acting on nanoparticles when creating a coating from suspension

Abstract

The analysis of data on the flow parameters of barium titanate nanoparticle suspensions at different concentrations and dynamic actions in the aspect of studying the destruction of particle aggregates was carried out in previous works [1-5]. Dynamic processes in macrosuspensions under the influence of vibration or ultrasound were described earlier [6-9]. Another form of sharp change in interacting connections between inclusions takes place during the formation of layers of particles on charged surfaces - electrophoretic coating under the action of an electric field [10-13]. Changes in the resulting forces of particles interaction in micro aggregates in both cases lead to a change in the macro-characteristics of the suspension flow, some rheological models of which were proposed and studied yet in [14-15]. In this paper, we propose and evaluate preliminary approaches for dynamic force formulas for that principal parts for electrophoretic coating for single particle from such suspensions and suggest next steps for further construction of the process equations in further work and verification of agreement with experimental data. It can be further noted that these studies are necessary for the next stage of creating new layered nanomaterials and developing small but powerful capacitors, acoustic sensors, etc.
