pH-Responsive Cellulose Nanocrystal Gels and Nanocomposites
Abstract
We show that functionalization of the surface of cellulose nanocrystals (CNCs) with either carboxylic acid (CNC–CO 2 H) or amine (CNC–NH 2 ) moieties renders the CNCs pH-responsive. At low pH, where the amine groups are protonated, CNC–NH 2 forms aqueous dispersions in water on account of electrostatic repulsions of the ammonium moieties inhibiting aggregation. However, a transition to hydrogels is observed at higher pH where the CNC–NH 2 are neutral and the attractive forces based on hydrogen bonding dominate. The opposite behavior is observed for CNC–CO 2 H, which are dispersible at high pH and form gels in an acidic environment. We further show that these pH-responsive CNCs can be incorporated into a poly(vinyl acetate) matrix to yield mechanically adaptive pH-responsive nanocomposite films.

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.
