Data supporting: Morphology modulation of ionic surfactant micelles in ternary deep eutectic solvents

This dataset contains raw and processed data in support of the named publication. This consists primarily of small-angle neutron scattering (SANS) data for mixtures of anionic and cationic surfactants in ternary deep eutectic solvents. Data files for differential scanning calorimetry (DSC) and viscosity measurements on the pure deep eutectic solvents are also included.

Data collection method:

Small-angle neutron scattering (SANS) measurements were carried out on the LOQ and Zoom instruments at ISIS Pulsed Neutron and Muon Source, UK. Mixtures either of sodium dodecyl sulfate (SDS), C12TAB and C16TAB (at concentrations of 25 mM and 130 mM) in choline chloride:urea:glycerol DES at different molar ratios were measured in various isotopic substitutions at 70 °C. The following measurements were carried out on pure choline chloride:urea:glycerol DES in molar ratios of 1:0.5:1.5, 1:1:1 and 1:1.5:0.5: - Differential scanning calorimetry: DSC measurements on the neat solvents were carried out on a TA Instruments DSC-Q20 differential scanning calorimeter. The sample was first equilibrated at 50 °C and held for 1 min, cooled to -75 °C at a ramp rate of 10 °C min-1 and held for 10 min, before heating to 30 °C at a ramp rate of 5 °C min-1 . - Viscosity: The viscosity of the solvents was measured using a TA Instruments HR-3 Discovery Hybrid Rheometer operating in flat plate geometry with Peltier temperature control. Viscosity data was obtained in a temperature range of 20 °C – 85 °C at a fixed shear rate of 1 s-1. The DES were measured as prepared, with a seal of mineral oil to prevent solvent interaction with the atmosphere during measurements.

Data processing and preparation activities:

SANS data were reduced using the routines within Mantid ( following the standard procedures on each instrument. The data were normalized to the sample transmission, calibrated to absolute units using a polymer standard and corrected for detector efficiencies, before scattering from the empty cell was subtracted. The resulting output was converted to absolute units of the scattering intensity (I(q), cm-1) vs. the momentum transfer (q, Å-1). Subtraction of the scattering from the pure solvents was performed afterwards using Igor Pro to account for the incoherent contribution to each sample.

Technical details and requirements:

Output data from the SANS experiment consists of .txt files in the standard 1D format of I(q) vs. q ( This data can be fitted using any available software capable of fitting SANS data. All other data is also given as .txt files and can be viewed and plotted using any suitable software.

Additional information:

All data files relating to the same experimental technique are grouped together in sub-folders. Files relating to DSC and viscosity measurements on the pure DES. A PDF file is included in the sub-folder containing SANS data which provides a brief description of the contents of each data file.
