Abstract

Cellulose nanocrystal films with different helical modulation lengths are characterized. Films are obtained by tuning the rate of evaporation and surface functionalization. Dielectric constant measurements are performed and the water confinement is estimated by employing the classical mixing model with randomly oriented ellipsoidal inclusions. The dielectric constant of absorbed water was found to be significantly smaller than that for free liquid, indicating a limited mobility due to binding with CNC matrix.
