pH‐Dependent Self‐Assembly: Micellization and Micelle–Hollow‐Sphere Transition of Cellulose‐Based Copolymers
Abstract
Simply by decreasing the pH of the medium, hydroxyethyl cellulose-graft-polyacrylic acid (HEC-g-PAA) can form micelles in water. Cross-linking the PAA chains at the periphery of the micellar core can efficiently lock the integrality of the micelles (see scheme). The resultant micelles transform into hollow spheres as the pH value increases. Both the micellization and the transition from micelles to hollow spheres are reversible. The hollow spheres show “on-off” character at a pH value of about 3.

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.
