The rise in need has led to the requirement of advanced smart materials to conquer the present and future disasters in energy storage and generation. Among various materials, metal organic framework (MOF) has been chosen as an active material with tunable structures, porous inorganic− organic structure, and flexibility, which allows it to play a vital role in synthesizing highly efficient energy material. In recent years, MOF materials have voiced remarkable energy storage efficiency and conversion by encouraging most of the challenges that are typically faced by transition metals, metal hydroxides, etc. Among various supercapacitor materials, nickel is a new class of electrode with excellent capacitance. To overcome some limitations, such as cyclic stability and low conductivity, researchers are working on tuning its structure and morphology. In this work, Ni-MOFs are synthesized by varying the solvent ratio using the hydrothermal method. The prepared N-0.5 MOF electrode material delivers a high specific capacity of 1004.67 C g −1 at 1 A g −1 current density. Furthermore, the hybrid supercapacitor device is fabricated using N-0.5 as the anode and activated carbon (AC) as the cathode, and its electrochemical performances are investigated in both the gel and aqueous electrolytes. All the results affirm that the prepared electrode material shows better electrochemical performance and serves as a suitable supercapacitor electrode.

“…Influenced by the previous reports on inorganic nanocomposites as lubricant additives, researchers showed great interest in the synergistic effects of MOF materials and other materials, and had successfully constructed a series of nanocomposites composed of MOFs and other components. 56–60 The experimental results showed that these nanocomposites reflected the synergistic effect of enhancing lubrication during friction, and improved the performance of lubricants to a greater extent. Table 2 shows the use of several nano-composite materials as lubricating oil additives reported in recent years.…”

A special “hard‐soft” MXene/Halloysite nanotube (HNTs)/ poly(amidoamine) (PAMAM) structure was constructed to improve the interfacial and tribological performances of fabric liner (FL) materials. Thereinto, the MXene/HNTs coating were successfully grafted onto fabric surface by electrostatic self‐assembly strategy, and a novel PAMAM dendrimer polymer terminated by amino groups was prepared via condensation reaction. The mechanical and tribological performances of MXene/HNTs/PAMAM@FL as well as wear mechanism were systematically evaluated. Specifically, the incorporation of MXene/HNTs/PAMAM coating enhanced the bonding strength by 62.4%, and declined the wear rate by 27.7% in comparison with pure FL. The splendid performance was ascribed to the synergistic effect of “soft” toughening PAMAM polymer and “hard” lubricating MXene/HNTs hybrids. The introduction of MXene/HNTs hybrids could enhance mechanical interlocking and bearing capacity. Then PAMAM polymer ameliorated interfacial adhesion and compatibility with resin via forming chemical bonds, which further reducing stress concentration through increased crack deflections due to the steric hindrance.Highlights MXene/HNTs/PAMAM coating was prepared via electrostatic self‐assembly and condensation reaction. Interfacial adhesion of fabric liner achieved effective promotion. High‐quality tribofilm was constructed by the synergistic enhancement effect between MXene/HNTs particles and PAMAM polymer. The tribo‐chemical reactions participate in improving the lubricity and durability of tribofilm.
