This proposal is part of a project based on understanding the formation of gels in suspensions of partially oxidised cellulose nanofibrils and small amounts of additives, such as surfactants, salt and clays, which are of interest as sustainable viscosity modifiers in aqueous formulations. Due to shrinking oil reserves and the environmental persistence of these, often toxic, molecules the use of ¿green thickeners¿, such as cellulose, is currently being investigated. In this proposal we like to use SANS2d to investigate the gel formation of oxidised cellulose with non-ionic surfactants (TEGC and OEGC) and an anionic surfactant (AOT) and mixtures of these surfactants with H and D-SDS. We need to use SANS2d because of its extended q-range as our previous measurements with SDS showed that the interesting features in these structures can only be measured at low q.
