Nonionic surfactant mixtures in an imidazolium-type room-temperature ionic liquid.
The physicochemical properties of nonionic surfactant mixtures in an aprotic, imidazolium-type room-temperature ionic liquid (RT-IL) have been studied using a combination of static surface tensiometry, dynamic light scattering (DLS), and cryogenic transmission electron microscopy (cryo-TEM). The surfactants used in this study are phytosterol ethoxylates (BPS-n, where n is an oxyethylene chain l...
متن کاملPhase behavior of phytosterol ethoxylates in an imidazolium-type room-temperature ionic liquid.
The temperature-concentration phase behavior of nonionic surfactants in an aprotic imidazolium-type room-temperature ionic liquid (RT-IL) was evaluated on the basis of a combination of visual appearance, polarized optical microscopy, and small angle X-ray scattering data. Phytosterol ethoxylates (BPS-n, where n denotes oxyethylene chain lengths of 5, 10, 20, and 30) were used as surfactants in ...
متن کاملExcess electron solvation in an imidazolium-based room-temperature ionic liquid revealed by ab initio molecular dynamics simulations.
We present the first approach to the excess electron solvation in a novel medium, room-temperature ionic liquid, using ab initio molecular dynamics simulation techniques in this work. Results indicate that an excess electron can be solvated in the [dmim](+)Cl(-) IL as long-lived delocalized states and two short-lifetime localized states, one a single-cation-residence parasitical type and the ot...
متن کاملOrdering in Mixtures of a Triblock Copolymer with a Room Temperature Ionic Liquid
Well-ordered block copolymer (BCP) morphologies are obtained by blending PEO-PPOPEO triblock copolymer surfactants with the room temperature ionic liquid (IL) 1-butyl-3-methylimidazolium hexafluorophosphate. The selective association of the IL with the PEO blocks increases the segregation strength by raising the effective interaction parameter between the PEO and PPO blocks. Therefore, the copo...
متن کاملRoom temperature ionic liquid-lithium salt mixtures: optical Kerr effect dynamical measurements.
The addition of lithium salts to ionic liquids causes an increase in viscosity and a decrease in ionic mobility that hinders their possible application as an alternative solvent in lithium ion batteries. Optically heterodyne-detected optical Kerr effect spectroscopy was used to study the change in dynamics, principally orientational relaxation, caused by the addition of lithium bis(trifluoromet...
