WebCNCs have rod-like structures with a high aspect ratio， which makes them ideal building blocks for the formation of cholesteric（chiral nematic） liquid crystals（LCs）. In general， the CNCs suspension in a glass vial undergoes phase separation into a cholesteric LC bottom phase and an isotropic top phase[19].
