Characterization of CNF Thixotropy

Caption

Characterization of CNF thixotropy. (a) Stimulus responsiveness of CNF hydrogel for stress, sonication, pH, and cation factors (white spots in the hydrogel are micro-bubbles formed by cavitation during vortex agitation). (b) Range of storage modulus (G?) obtained with various stimulus factors. (c) Injection of CNF hydrogel in a cylindrical mold. The hydrogel was injected in a low-viscosity state, enabling its delivery, but rapidly recovered its consistency after being deposited, retaining the shape of the mold. (d) Additional examples of shape conformation after injection. The hydrogel conformed to complex structures and narrow spaces before returning to its solid state.
