Abstract

Flexible reduced graphene oxide (rGO) sheets are being considered for applications in portable electrical devices and flexible energy storage systems. However, the poor mechanical properties and electrical conductivities of rGO sheets are limiting factors for the development of such devices. Here we use MXene (M) nanosheets to functionalize graphene oxide platelets through Ti-O-C covalent bonding to obtain MrGO sheets. A MrGO sheet was crosslinked by a conjugated molecule (1-aminopyrene-disuccinimidyl suberate, AD). The incorporation of MXene nanosheets and AD molecules reduces the voids within the graphene sheet and improves the alignment of graphene platelets, resulting in much higher compactness and high toughness. In situ Raman spectroscopy and molecular dynamics simulations reveal the synergistic interfacial interaction mechanisms of Ti-O-C covalent bonding, sliding of MXene nanosheets, and π-π bridging. Furthermore, a supercapacitor based on our super-tough MXene-functionalized graphene sheets provides a combination of energy and power densities that are high for flexible supercapacitors.

  • Good conductivity of MXene and intimate electrical contacts among NCSe, MXene via macroscopic rGO films predispose low internal resistance and high conductivity.

    “(2) good conductivity of MXene and intimate electrical contacts among NCSe, MXene via macroscopic rGO films that predispose low internal resistance and high conductivity [94]”

    From Rationally designed multifunctional Ti3C2 MXene@Graphene composite aerogel integrated with bimetallic selenides for enhanced supercapacitor performance and overall water splitting (2022) · cites this paper as [94]

    The Results (Mechanical properties of the graphene sheets; page unavailable) attribute the high conductivity of MXene-functionalized rGO sheets to MXene and report increased sheet conductivity after functionalization. The paper does not address NCSe or establish that electrical contacts among NCSe, MXene, and rGO films produce low internal resistance. (LLM, conf=0.88)

    Experimental — accuracy not yet measured

  • The presence of exfoliated MXene is confirmed by the characteristic Eg group vibrations at M:GO 5:6.

    “confirming the presence of the exfoliated MXene [29, 33]”

    From Hybrid MXene/reduced graphene oxide aerogel microspheres for hydrogen evolution reaction (2021) · cites this paper as [29]

    The Results section, under “Synthesis and characterization of the graphene sheet,” identifies Eg group vibrations in the Raman spectrum as expected for exfoliated MXene. It does not report that finding at an M:GO ratio of 5:6; the composition-specific part of the claim is unsupported by this source. (LLM, conf=0.86)

    Experimental — accuracy not yet measured

  • The merging of the MXene (002) peak with the GO (001) peak at M:GO 5:6 might be due to interaction between GO and MXene.

    “which might be due to the interaction between the GO and MXene [20, 29]”

    From Hybrid MXene/reduced graphene oxide aerogel microspheres for hydrogen evolution reaction (2021) · cites this paper as [29]

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.
