Supramolecular Hydrogel of Chitosan in the Presence of Graphene Oxide Nanosheets as 2D Cross-Linkers

Han, Donglin, Yan, Lifeng·2014·ACS Sustainable Chemistry & Engineering

Abstract

Biomass-based materials are attractive due to their renewability, biodegradability, and biocompatibility. Chitosan is a typical biomacromolecule that can be used as feedstock for novel materials. Here, the self-assembly of chitosan chains with graphene oxide (GO) nanosheets has been studied, where GO works as the two-dimensional cross-linker dues to its multifunctional groups on both sides. Supramolecular hydrogels of chitosan and GO have been prepared by controlling the concentration of GO, ratio of chitosan to GO, and temperature. It was found that at high GO concentration, hydrogel can be obtained at room temperature, and the as-prepared hydrogel showed a self-healing performance. However, at low GO concentration, the supramolecular hydrogel formed only at high temperature (95 °C). The driving force for the hydrogel is believed to be the noncovalent interactions. The reversible hydrogels have potential applications in fields of biomaterials, wastewater treatment, and smart materials.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The beneficial influence of GO is related to the mechanical stability of the CS-GO supports, maintaining surface area and porosity, thereby giving a better metal-support interaction with the Pd nanoparticles.

    “According to the literature [27], the beneficial influence of GO should be related to the mechanical stability of the CS-GO supports, maintaining surface area and porosity, thereby having a better metal-support interaction with the Pd NPs.”

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.
