Salt effects on gelation of oxidised cellulose nanofibrils with nonionic surfactants

Abstract: Our group has been studying partially oxidised anionic cellulose (AC) nanofibrils which form gels in the presence of moderate salt concentrations and with anionic surfactants. Nonionic surfactants alone have little effect upon the viscosity of AC suspensions however if a small amount of salt is added gels form, at much lower concentrations than needed to gel the fibrils with salt alone. Therefore we would like to study the structure of both the non-ionic micelles and AC gel network structures in these systems to understand the interactions causing this variation in rheological behaviour. Selective deuteration will enable us to highlight the cellulose gel structures and the location of surfactant within them. Understanding the structures formed in these suspensions will enable rational use of AC components in future, more environmentally friendly, aqueous formulations.
