Temperature was controlled via a Peltier unit (±0.1 °C) and kept at 25 °C. A thin layer of low viscosity mineral-oil was added to the edge of the geometry to prevent sample evaporation. Oscillatory amplitude sweeps were done at a fixed angular frequency (ω) of 6.28 rad·s-1 and amplitude strain (γ) from 0.01 to 100%. Frequency sweeps were conducted at γ of 0.1%, within the linear viscoelastic range, covering ω of 0.01 to 50 rad·s-1. All samples were measured between 24 and 48 hrs after preparation. Small-angle neutron scattering (SANS) measurements were conducted on the time-of-flight diffractometer instrument SANS2d at the STFC ISIS Neutron and Muon Source (Didcot, UK). Incidental wavelengths from 1.75 to 16.5 Å were used with a sample-to-detector distance of 4 m, corresponding to a total scattering vector range q from 4.5 × 10-3 to 0.75 Å-1. The sample temperature was controlled by an external circulating thermal bath (Julabo, DE). The scattering intensity was converted to the differential scattering cross-section in absolute units using ISIS standard procedures. Samples were loaded in 1 mm path length, 1 cm wide optical quartz cells. Constrast match experiments were done at 15 wt% D2O, which is the contrast match point for the surfactant mixtures. All other SANS experiments were done in 100 wt% D2O. en 1 10.15125/BATH-00797 https://doi.org/10.1039/D0SM00135J pub HR3 Discovery Hybrid Rheometer 9f2fdb2d-c645-45f3-be3d-b8e64f220c5d open
