Title: A model provides insight into electric field-induced rupture mechanism of water-in-toluene emulsion films,
Abstract: This paper presents the first MD simulations of a model, which we have
designed for understanding the development of electro-induced instability of a
thin toluene emulsion film in contact with saline aqueous phase. This study
demonstrates the charge accumulation role in toluene film rupture when a DC
electric field is applied. The critical value of the external field at which
film ruptures, thin film charge distribution, capacitance, number densities and
film structure have been obtained in simulating the system within NVT and NPT
ensembles. A mechanism of thin film rupture driven by the electric discharge is
suggested.We show that NPT ensemble with a constant surface tension is a better
choice for further modeling of the systems that resemble more close the real
films.
