The “head” part of surfactant molecules consist of a polar or ionic group. The “tail” of many surfactants consist of a single hydrocarbon chain whereas that of some other surfactants, e.g., phospholipids, are made of two hydrocarbon chains both of which are connected to the same head. In contrast, gemini surfactants2–5, consist of two single-chain surfactants whose heads are connected by a “spa...

The influence of surfactants is great importance to the interfacial properties, which related by characteristics molecular arrays at interface multicomponent and multiphase systems. Comparing with single type surfactant, mixtures usually provide superior performances in improving properties oil-water application enhanced oil recovery. In this study, dynamics simulations were employed explore me...
