“…Extensive research is still underway using MBE to achieve high-quality TI crystals including Bi 2 Te 3 and Bi 2 Se 3 which are the material of choice for the study of magneto-transport properties due to strong spin–orbit coupling (Fig. 8 b) [ 109 ]. However, several critical 2D compounds of Bi including chalcogenides have not been realised with lateral sizes larger than 100 µm by CVD methods [ 112 ].…”

“…Also, the polymer nanocomposite synthesis via incorporation of the particles or twodimensional (2D) materials having dimensions in the nanometre range into the polymer matrix perceives useful implications for the progress of futuristic materials. [53] The key aspects here lie in the consideration of enhanced surface area due to the small size of the incorporated entities, forces per unit mass resulting from the interactions between the surface and surrounding area. Further, a better-interconnected conduction pathway for ions within the membrane and polymer matrix can be achieved by 1D polymer fiber.…”

In the present exploration, MXene (Ti 3 C 2 T x ) based composite polymer electrolytes (CPEs) are fabricated by electrospinning technique to make free-standing fiber films. In this process, four different composite polymer electrolytes (CPEs) are synthesized by varying the MXene content from 0 mg to 60 mg in poly-acrylonitrile (PAN) along with NaPF 6 solution. The electron microscopic studies reveal the layered morphology of synthesized MXene samples. Further, MXene based CPE fibers exhibit lengths of several micro-meters with widths < 3 μm. The linear sweep voltammetry results manifest the electrochemical stability of CPE S up to 3.3 V. The key studies in this research work are the incorporation of sodium-based salts which are more abundant, less expensive, less reactive, and environment friendly than other Li based salts, also the highlighted findings have been assigned to the impedance and the DC polarization, which illustrate the enhanced ionic conductivities (of the order of 10 À 6 S/cm) for the 20 mg MXene based CPE sample. Further, the Fourier Transform Infra-Red (FTIR) spectroscopy analysis and its deconvolution studies have been carried out, which depict the enhancement in the free ion concentration in the MXene based CPEs samples.
