“…The partial phase diagram of Brij30/[Bmim]PF 6 /H 2 O system has been determined by Friberg et al [15]. In the present report, we focus our attention on the lamellar liquid crystal region shadowed and labeled by La (Fig.…”

“…As a kind of co-surfactant, ILs are superior to alcohol because of its negligible vapor pressure, high stability and viscosity. Friberg et al [15] have studied the solubilization of ionic liquid [Bmim]PF 6 in the La phase of Brij30/water system, and the results show that IL can be solubilized into the La phase without changing the dimensions of the amphiphile layer. Wang et al [16] have determined the phase diagram of ternary system of Brij97/ionic liquid/water and investigated the location of ionic liquid in the hexagonal liquid crystal.…”

The microstructure of lamellar liquid crystal composed by nonionic surfactant polyoxyethylene laurylether (Brij30), room temperature ionic liquid 1-butyl-3-methylimidazolium hexafluorophosphate ([Bmim]PF 6 ) and water is investigated by deuterium nuclear magnetic resonance ( 2 H NMR) and rheological techniques. And the lubrication properties of the lamellar mesophase are determined to illustrate their relationship with the microstructure. The results show that the structure strength of the lamellar phase is enhanced with increasing amount of Brij30, so the anti-wear capacity of the lamellar phase is improved. But, both of the structure strength and lubrication properties are impaired with increasing water content in the system due to the increased interlayer space and the penetration of water into the amphiphile bilayer. However, though the structure of the lamellar phase is disturbed by [Bmim]PF 6 , the lubrication properties are still improved due to the inherent lubrication properties of [Bmim]PF 6 .

“…An early review of ionic liquids in microemulsions [28] included cases wherein IL was substituted for an oil in water/IL/surfactant microemulsions [44][45][46], IL was substituted for water in IL/oil/surfactant microemulsions [47][48][49], and IL was substituted for surfactant in water/oil/IL microemulsions [15,16,50,51].…”

“…Prior to the work by Armstrong and co-workers, 36 limited work had been done on the dissolution of surfactants in ILs 6 or ionic liquids in aqueous surfactant solutions. 37 This new work showed us that [BMIM]Cl and [BMIM]PF 6 support the formation of micelles. Taken together, these support our premise that ILs can be utilized in the formation of microemulsions.…”

As the results after one year will indicate, this project will provide the information and outline for development of a novel decon/detox cleaning formulation. The emphasis during this year has been on the oxidative decontamination/detoxification of surrogates for mustard and phosphorous nerve agents. More work was expended in developing a literature survey, because the ability to do laboratory work was restricted by competing projects. The intent was to resume in the fall, but the second year's funding was cut. Therefore, this final report will be a complete literature presentation and a detailed outline of future work. BackgroundWe established our goal to develop formulations of superior cleaning agents that catalyze chemical reactions. In order to accomplish this we reasoned that the ability of room temperature ionic liquids (ILs) dissolved in aqueous ethanol (aq EtOH) to solubilize and promote the oxidation of three chemical agent surrogates was feasible. Such a series of cleaning agents, we believe, would have immediate use in chemical detoxification and decontamination of a wide range of contaminants of importance to the Department of Defense (DoD).The ILs, as will be seen, bear strong chemical resemblance to surfactants.
