All-cellulose nanocomposites reinforced by cellulose nanocrystals (CNC) were produced
using a solvent consisting of 1-butyl-3-methylimidazolium chloride and dimethyl sulfoxide.
Microcrystalline cellulose (MCC) was pre-dissolved at high temperature in the solvent.
Freeze-dried CNC were then added to the slurry at room temperature, thereby avoiding
complete CNC dissolution. Solid all-cellulose composite films were obtained by film casting,
solvent exchange and drying. The MCC to CNC ratio was kept constant while the solvent …

Humidity-controlled dynamic mechanical analysis (RH-DMA) is a powerful tool that can be
used to measure the loss and storage modulus of hydrophilic materials as a function of
humidity, thereby providing an insight into the water-induced plasticisation mechanisms. In
our study, we showed that the all-cellulose composites (ACC). In order to provide an insight
into their peculiar behaviour dictated by their matrix but also by a percolated cellulose
nanocrystal network acting as a reinforcement, a simple mathematical model in the form of a …
