The effect of water on the shape of aggregates in water-in-oil microemulsions according to data of computer simulation

Аннотация

A sodium 1,4-bis[(2-ethylhexyl)oxy]-1,4-dioxybutane-2-sulfonate (NaАОТ)–water–isooctane three-component system is calculated by the molecular-dynamics method. In a wide range of relative water contents w₀, reverse micelles are obtained with different morphologies: single spherical and cylindrical micelles and their spatial networks. It is shown that w₀ and surfactant concentration are the main shape-generating factors. The data obtained are in good agreement with previous results of simulations and experimental data.
