Parameters Affecting the Chiral Nematic Phase of Nanocrystalline Cellulose Films
Abstract
Nanocrystalline cellulose (NCC) is extracted from woody biomass using acid hydrolysis. It has unique strength and distinctive optical/conductive/magnetic properties. When a suspension of NCC is air-dried, it forms a film with unique characteristics (e.g., iridescence) linked to the formation of chiral nematic structure. In this contribution, the effects of ionic strength, temperature, suspension concentration, and exposure to magnetic field on the morphology of NCC are examined. The influence of these parameters on chiral nematic phase is investigated at a macroscopic level using circular dichroism and polarized microscopy. It is demonstrated that the addition of salt to NCC suspensions, NCC concentration, temperature, and the presence of a magnetic field all have an effect on the pitch of the chiral nematic structure. For example, drying of the NCC film in the presence of a 0.2 T external magnetic field increases the pitch, in a manner dependent on drying time. The implication of these results for the structure and properties of NCC is discussed.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
