“…The PCT hydrogel with a Ti 3 C 2 Tx content of 0.31 wt% showed 1.9 × 10 −4 MPa of E value. The soft PCT hydrogels exhibited better stretchable, indicating that a large amount of energy is dissipated during the hydrogel stretching process 53 and can resist external damage well. Moreover, the low cross‐linked hydrogel has a larger surface area, which allows more active sites to be produced and thus improves electrochemical performance 54,55 .…”

Lightweight, thin, and stretchable flexible microelectronic devices have become a new challenge for researchers. To provide power for these conformable devices, it is necessary to design the energy storage device into a flexible and stretchable structure. In this paper, a two‐step method was used to prepare a dual‐physical cross‐linked polyacrylic acid/chitosan/Ti3C2Tx(PCT) conductive hydrogel flexible electrode. The three‐dimensional (3D) porous structure not only offers a good electrical connection, but also saves the use of binder and additional current collector, which helps to enhance the electrochemical properties of electrode. The unique two‐dimensional layered structure of Ti3C2Tx enables the hydrogel electrode to withstand considerable pressure deformation without breaking, and has excellent tensile properties. The flexible electrode exhibited an excellent tensile strength of 0.083 MPa if only introduced 0.31 wt% of Ti3C2Tx with the tensile strain of 158.63% and owned remarkable self‐healing properties after injury. Thereby, the hydrogel electrode renders a maximum capacitance of 291.8 mF g−1 at 0.5 mA/g and a good cycling stability with 64.24% capacitance retention after 2000 charge–discharge cycles. This provides a research and development strategy for binder‐free, non‐toxic, and mini‐size flexible energy storage devices.

“…[73] A variety of MXenes based skin-mountable devices such as tattoo sensor attached to various parts of body, hydrogel nanocomposites for biosignal sensing, and hydrogel sensor for strain sensing have been demonstrated due to their flexibility, conductivity, and good electrochemical properties within recent years. [74][75][76] TMDCs, another resourceful 2D materials, have been highlighted for skin-mountable electronics because of their moderate bandgap in the range of 1.1-2.5 eV, which provides unique optical and electrical properties hardly found in graphene. TMDCs possess the layered structure, where two chalcogen layers (S, Se, or Te) are seperated by hexagonally close-packed transition metal (Mo, W, V, Ti, etc.).…”

Two-dimensional (2D) nanomaterials have attracted increased interest and exhibited extended applications from nanotechnology to materials science, biomedicine, tissue engineering, as well as energy storage and environmental science. With the development of the synthesis and fabrication of 2D materials, a new family of 2D materials, metal carbides (MCs), revealed promising applications in recent years, and have been utilized for the fabrication of various functional 2D and three-dimensional (3D) nanomaterials for energy and environmental applications, ascribing to the unique physical and chemical properties of MCs. In this review, we present recent advance in the synthesis, fabrication, and applications of 2D and 3D MC-based nanomaterials. For this aim, we first summarize typical synthesis methods of MCs, and then demonstrate the progress on the fabrication of 2D and 3D MC-based nanomaterials. To the end, the applications of MC-based 2D and 3D materials for chemical batteries, supercapacitors, water splitting, photodegradation, removal of heavy metals, and electromagnetic shielding are introduced and discussed. This work provides useful information on the preparation, hybridization, structural tailoring, and applications of MC-based materials, and is expected to inspire the design and fabrication of novel and functional MXene materials with improved performance.
