Our new article “Effects of fibre dimension and charge density on nanocellulose gels” has been published in Journal of Colloid and Interface Science. This study investigated the effect of pulp source on the nanocellulose fibre dimension and gel rheology. The findings show that nanocellulose fibres extracted from softwood and hardwood pulp exhibit similar width but different length dimensions. Rheological measurements show that the dynamic moduli of nanocellulose gels are independent of pulp source and are mostly influenced by fibre concentration. Differences in the steady-state behaviour (i.e. viscosity) at constant surface charge can be attributed to differences in fibre length. Increasing the surface charge density influences the critical strain and the viscosity at the percolation concentration (0.1 wt%) due to higher electrostatic interactions.
