TL;DR: The stimuli-responsive morphological transitions in the self-assembly of the reported anionic surface active ionic liquids (SAILs) will be useful for encapsulation and delivery of active (bio)molecules in the targeted biomedical applications.
Abstract: Dodecylbenezenesulfonate-based anionic surface active ionic liquids (DBS-ILs) paired with onium cations, n-butyltrimethylammonium ([N1114]), 1-butyl-3-methylimidazolium ([C4mim]), and N-butylpyridinium ([C4Py]) have been synthesized. DBS-ILs were found to be highly surface active having critical micelle concentration (CMC) lower than that of their conventional analogue sodium dodecylbenezenesulfonate ([Na][DBS]). The CMC values of DBS-ILs were determined from surface tension (ST) and isothermal titration calorimetry (ITC). DBS-ILs formed micelles predominantly in the aqueous medium, and unlike [Na]DBS, the micelles of DBS-ILs could be transformed into vesicles with the addition of sodium bromide (NaBr). Micelle to vesicle transitions (MVTs) were evidenced from dynamic light scattering (DLS), turbidity, proton nuclear magnetic resonance (1H NMR), and cryo-TEM techniques. Thermodynamics of aggregation was investigated from ITC which indicated that the aggregation process is primarily driven by the entropy f...

TL;DR: The most prominent correlation for density and surface tension for all the multicomponent mixtures have been evaluated and the most prominent polynomial or linear regressions were obtained as discussed by the authors.
Abstract: Room temperature ionic liquids (RTILs) have been ascribed as alternative solvents in separation processes or chemical reactions This research is concerned with the study of density, ρ, viscosity, η, and surface tension, σ, over the mole fractions of (01000 to 1000) mol and temperature from (29315 to 33315) K for ternary mixtures of 1-ethyl-3-methylimidazolium diethylphosphate (EMIM DEP)/1,3-dimethylimidazolium dimethylphosphate (MMIM DMP), water, and 1-propanol/2-propanol As the temperature increased, surface tension and density results for all the multicomponent mixtures show a linear descending trend Adversely, viscosity results indicate polynomial descending trend At the whole ranges of temperature, the density, surface tension and viscosity data show a significant gap between mole fractions of ionic liquid These experimental results have been evaluated and the most prominent polynomial or linear regressions were obtained The most prominent correlation for density and surface tension for all

TL;DR: In this article, the interaction between GO and AMICl molecules as well as the effects of GO-IL on the mechanical properties, thermal conductivity and solvent resistance of SBR were thoroughly studied.
Abstract: Ionic liquid 1-allyl-3-methyl-imidazolium chloride (AMICl) is used to fine-tune the surface properties of graphene oxide (GO) sheets for fabricating ionic liquid functionalized GO (GO-IL)/styrene-butadiene rubber (SBR) nanocomposites. The morphology and structure of GO-IL are characterized using atomic force microscope, X-ray diffraction, differential scanning calorimetry, X-ray photoelectron spectroscopy, Fourier transform infrared spectroscopy, UV-vis spectra and Raman spectra. The interaction between GO and AMICl molecules as well as the effects of GO-IL on the mechanical properties, thermal conductivity and solvent resistance of SBR are thoroughly studied. It is found that AMICl molecules can interact with GO via the combination of hydrogen bond and cation–π interaction. GO-IL can be well-dispersed in the SBR matrix, as confirmed by X-ray diffraction and scanning electron microscope. Therefore, the SBR nanocomposites incorporating GO-IL exhibit greatly enhanced performance. The tensile strength, tear strength, thermal conductivity and solvent resistance of GO-IL/SBR nanocomposite with 5 parts per hundred rubber GO-IL are increased by 505, 362, 34 and 31%, respectively, compared with neat SBR. This method provides a new insight into the fabrication of multifunctional GO-based rubber composites. Copyright © 2016 John Wiley & Sons, Ltd.
