The structure of dispersions of TEMPO-oxidised cellulose nanofibrils at various concentrations, in water and in NaCl aqueous solutions, was probed using small angle X-ray scattering and results were compared with rheology.
Using small-angle X-ray scattering (SAXS), we obtained direct experimental evidence on the structure of hydrated polyatomic anions, with hydration effects starkly different from those of cations (J. Chem. Phys., 2011, 134, 064513).
