We have developed a coarse-grained model for the aqueous solution of an acrylic copolymer and a surfactant. We use the method of dissipative particle dynamics [1-3]. Electric charges on surfactant molecules and counter-ions are taken into account explicitly, and we use for electrostatic interactions the computational scheme developed in Ref.[2]. The aim is to study the structure and to perform the analysis of stability of micelles in polymer/surfactant solutions, as well as to search for optimal conditions of a film formation from aqueous solutions of polymer micelles stabilized by surfactants. To model the film formation we apply an algorithm for evaporation of the solvent (water). As an illustration of the capabilities of the computational scheme, we demonstrate our results of the influence of various parameters of the model (concentration of components, parameters of volume interaction and of electrostatic interaction) on the characteristics of the emerging films.
