Research progress of MXenes and layered double hydroxides for supercapacitors

“…Although LDH materials have become an attractive candidate for ultra-high energy storage capacitor materials due to outstanding theoretical capacitance and low cost, [130][131][132][133][134][135][136] the original LDH nanostructures have serious defects, including weak stability of the microstructure, poor conductivity, limited ion/electron transfer rate, surface re-stacking hinders the accessibility of the structure, and poor magnification performance and cycle stability in practical applications. 39,[137][138][139][140] Surprisingly, LDH materials can better interact with high-performance 2D materials through the -OH group on the surface to form solid nanocomposites.…”

Ultrathin and flexible polyimide/Ti3C2TX MXene composite films for electromagnetic interference shielding with harsh environment tolerance

“…[25][26][27] However, the inherent poor mechanical properties and high susceptibility to oxidation of MXene materials hinder their practical application. [28][29][30][31] The most common method for improving the mechanical properties of MXenes is to introduce a polymer matrix to compensate for their deficiencies through the excellent mechanical properties of the polymer itself. [32][33][34][35][36][37][38][39][40] Gogotsi et al 41 fabricated polyvinyl alcohol (PVA)/Ti 3 C 2 T X composite films with excellent mechanical properties by vacuum-assisted filtration.…”

Mangifera indica stone-assisted layered double hydroxide biocomposites: efficient contenders for reactive dye adsorption from aqueous sources

“…33,34 Currently, layered double hydroxide (LDH) materials are gaining attention as a prominent candidate for biocomposite synthesis and also find application in various advanced fields including drug delivery, 35 electrolytic water splitting, 36 and supercapacitors. 37 The synergistic effect of LDH with biomass shows a significant improvement in physicochemical properties such as stability, functional groups, increased surface area and structural heterogeneity. 38,39 Basically, LDHs are synthetic anionic clays with a 2D nanostructure like hydrotalcites with brucite-like layers.…”
