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.
