“…MXenes can be easily assembled to form interlayer hydrogen-bonded hybrid films through VAF, and a wrinkle-like structure is usually distributed throughout the whole surface of the MXene membrane because of the unique ultrathin flakes and abundant terminal groups of MXene [76]. Using VAF, substantial efforts have been devoted to fabricating laminar membranes by combining MXene with other materials.…”

A growing family of two-dimensional (2D) transition metal carbides or nitrides, known as MXenes, have received increasing attention because of their unique properties, such as metallic conductivity and good hydrophilicity. The studies on MXenes have been widely pursued, given the composition diversity of the parent MAX phases. This review focuses on MXene films, an important form of MXene-based materials for practical applications. We summarized the synthesis methods of MXenes, focusing on emerging synthesis strategies and reaction mechanisms. The advanced assembly technologies of MXene films, including vacuum-assisted filtration, spin-coating methods, and several other approaches, were then highlighted. Finally, recent progress in the applications of MXene films in electrochemical energy storage, membrane separation, electromagnetic shielding fields, and burgeoning areas, as well as the correlation between compositions, architecture, and performance, was discussed.

“…Two peaks located at 457.7 and 463.5 eV are attributed to Ti-C, and the other two peaks at 458.6 and 464.1 eV are attributed to Ti-O, which match well with the reported pure MXene. 59…”

In situ synthesis of NiCo based metal-organic framework (MOF) nanosheets and the exfoliation of Ti 3 C 2 T x into isolated nanosheets (MXene), called, NiCo-MOF/Ti 3 C 2 T x hybrid nanosheets, are simultaneously achieved by a facile ultrasonic method. This method can effectively avoid the oxidation and restacking of Ti 3 C 2 T x nanosheets, and also make them uniformly disperse on the surface of NiCo-MOF. The formed NiCo-MOF/Ti 3 C 2 T x hybrid nanosheets achieve a high specific capacitance of 815.2 A g-1 at 1 A g-1. The practical asymmetric supercapacitor (ASC) is fabricated using activated carbon and NiCo-MOF/Ti 3 C 2 T x hybrid nanosheets. The ASC device achieves an energy density of 39.5 Wh kg-1 at a power density of 562.5 W kg-1 , and also demonstrates a suitable cycling stability with 82.3 % of capacitance retention after 10000 continuous cycles at 5 Ag-1. The enhanced electrochemical property of NiCo-MOF/Ti 3 C 2 T x is attributed to the nanosheet-like and mesoporous structure, high electronic conductivity, and synergistic effect of hybrid electroactive components.

“…A detailed overview can be found in another review paper. A common strategy is to add conductive materials to form composite electrodes, [58] though additive-free MOF-based supercapacitors have also been reported with relatively disadvantageous electrochemical properties. [49][50][51][52][53] MXenes are usually found in a M n+1 X n T x phase where M is a transition metal, X is either carbon or nitrogen, and T represents surface termination.…”

Emerging health monitoring bioelectronics require energy storage units with improved stretchability, biocompatibility, and self‐charging capability. Stretchable supercapacitors hold great potential for such systems due to their superior specific capacitances, power densities, and tissue‐conforming properties, as compared to both batteries and conventional capacitors. Despite the rapid progress that has been made in supercapacitor research, practical applications in health monitoring bioelectronics have yet to be achieved, requiring innovations in materials, device configurations, and fabrications tailored for such applications. In this review, the progress in stretchable supercapacitor‐powered health monitoring bioelectronics is summarized and the required specifications of supercapacitors for different types of application settings with varying demands on biocompatibility are discussed, including nontouching wearables, skin‐touching wearables, skin‐conforming wearables, and implantables. The perspective of this review is then broadened to focus on integration of stretchable supercapacitors in bioelectronics and aspects of energy harvesting and sensing. Finally further insights on the existing challenges in this developing field and potential solutions are provided.
