Résumé
Cellulose nanocrystals are slender, negatively charged nanoparticles that spontaneously form a cholesteric liquid crystal in aqueous suspension above a critical concentration. When they are suspended in apolar solvents such as toluene using surfactants, the application of an AC electric field leads to the reorientation and then distortion of the cholesteric order until the cholesteric structure completely unwinds into a nematic-like order, typically above 0.4-0.6 kV/cm at 1kHz. In this work, we show that at much higher electric fields ( The online version contains supplementary material available at 10.1007/s10570-023-05391-6.
