for pressure,
volume, temperature dependencies of its viscosity and density. The
compression of a 2.0 wt % cellulose nanocrystal suspension under 5.0
MPa at room temperature resulted in morphological changes from istotropic
to nematic form. However, at high temperature, high-pressure treatment
caused desulfation and gelation. Those results have significant applications,
not only as additives in drilling and fracturing fluids but also for
the preparation of hydrogels.
