Toughened Hydrogels through UV Grafting of Cellulose Nanofibers
Abstract
The purpose of this research is to obtain toughened hydrogels by tailoring the interfacial interactions between cellulose nanofibers (CNFs) and a polymer matrix. To this end, a polymer matrix is grafted from the surfaces of CNFs to form a one-component nanocomposite hydrogel via a novel and green method, i.e., UV irradiation in the absence of an initiator. As a result, the toughness of this hydrogel is highly improved by 140.6% in contrast to the one with the same composition but an independent CNF–matrix architecture. We also find that hardwood-based CNFs result in more stretchable but softer hydrogels in contrast to softwood-based CNFs. It is revealed that the surface chemistry of CNFs plays an important role in fabricating such nanocomposites. We believe that UV grafting of CNFs may help fabricate various kinds of nanocomposites with good interfacial compatibility and interesting features.

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.
