Small angle neutron scattering (SANS) and rheology data on TEMPO-oxidised cellulose gels containing four different surfactants. All of the surfactants had the same hydrophobic tail length but had different headgroups: hexaethylene glycol mono-n-dodecyl ether (C12EO6, non-ionic), sodium dodecyl sulphate (SDS, anionic), cocamidopropyl betaine (CapB, zwitterionic) and dodecyltrimethylammonium bromide (DTAB, cationic). Data from contrast variation SANS studies are included where deuterated versions of C12EO6 or SDS, or varied D₂O/H₂O ratio of the suspensions (with CapB), were used to focus only on the structural properties of OCNF or surfactant micelles in the suspensions.

Normalized neutron and X-ray reflectivity data for Langmuir monolayers composed of mixtures of dimyristoylphosphatidylcholine, DMPC and a single 18-carbon tailed sulfobetaine, SB3-18 on pure water at room temperature and at surface pressures of 15 mN/m and 35 mN/m.Neutron measurements are carried out on D2O and air contrast matched water. Measurements were carried out with deuterated and hydrogenated lipids.

The dataset contains ASCII files for the following:- Small-angle neutron scattering (SANS) curves and fits for mixtures (mole ratios: 3:1, 1:1 and 1:3) containing polyoxometalate-headed surfactant(P2W17-2Cn, n= 12, 14, 16 and 18) and hydrogenated hexaethylene glycol monododecyl ether (C12EO6) as a function of surfactant total concentrations. Solutions are prepared in two different solvents: deuterium dioxide, 7:3 deuterium dioxide and H2O mixture.- SANS curves and fits for mixtures containing P2W17-2Cn surfactant (n = 12 and 14) and tail-deuterated C12EO6 (mole ratios: 3:1, 1:1 and 1:3) as a function of surfactant total concentrations. Solutions are prepared in deuterium dioxide.The dataset also contains Igor files for the following:- The plot of determination of critical micelle concentrations (CMC) of the mixed P2W17-2Cn/C12EO6 H2O system through surface tension measurements and conductivity measurements.
