“…Solar energy is considered to be a renewable and clean energy. Photothermal conversion materials can convert light energy into heat energy, which have attracted extensive attention in various fields such as energy storage, − seawater desalination, − sewage treatment, − viscous oil adsorption, , and photocatalysis. , However, photothermal materials are easily polluted in the outdoor environment, and so, it is imperative to develop self-cleaning photothermal materials. The superamphiphobicity refers to the contact angles of water (WCA) and oil on the surface greater than 150°.…”

In recent years, photothermal materials that can convert light into heat energy have attracted extensive attention. In this work, we report a simple and effective approach to construct a self-cleaning photothermal superamphiphobic fabric. Dopamine (DA) can self-polymerize into polydopamine (PDA) and adhere to the surface of cotton fabric as a secondary reaction platform. Then, SiO 2 nanoparticles were in situ grown on the PDA@fabric surface by the sol−gel method. The PDA clusters can not only provide good photothermal conversion performance but also be integrated with SiO 2 to create micro−nano rough structures. Finally, the surface of SiO 2 was modified by the long chain of fluorosilane to decrease the fabric surface energy, resulting in superamphiphobicity. The contact angles of water, ethylene glycol, and pump oil on the modified fabric surface could reach 161.1, 158.1, and 142.2°, respectively, making the fabric resistant to contamination by water, common beverages, and oil. Due to the adhesion of the PDA layer, the strong binding force between the fabric and SiO 2 particles enabled the modified fabric to withstand various chemical and mechanical attacks, showing excellent mechanical robustness and harsh environmental stability. More importantly, the surface temperature of the modified fabric could be increased from 19.6 to 37.0 °C, which is close to the human body temperature, under the irradiation of simulated sunlight (I = 15 A, 300 s). The photothermal superamphiphobic fabrics with self-cleaning properties show great promise in the photothermal conversion field.

“…In order to find a solution for the scarcity of fossil fuels, one of the biggest problems in the world, the search for economical and sustainable energy conversion and storage systems continues unabated. , In addition to the environmental pollution of fossil fuels, they will run out in the coming years, which is also a major problem. Therefore, it is of great importance to find an alternative, clean, and low-cost method to store energy that meets the world’s demands. − Two important candidates to help us get out of this global energy crisis are batteries and supercapacitors (SCs). − The biggest advantage of batteries compared to other storage devices is that batteries have very large volumetric energy densities and can be applied in the field of compressible electronics. However, the temperature dependence of batteries and their low power densities limit their applications. − On the other hand, SCs can be divided into two categories based on their energy storage methods.…”

Developing flexible, lightweight, and portable energy storage systems have become a necessity with the advent of wearable electronic devices in modern society. We report a novel, easy, and low-cost way to fabricate flexible bimetallic metal–organic framework (MOF) doped graphene sponge (GS) free-standing materials (ZnCo-MOF/GS). The electrochemical behavior of the flexible ZnCo-MOF/GS was probed via galvanostatic charge–discharge, electrochemical impedance spectroscopy, and cyclic voltammetry. The morphological and structural studies of this material were performed by scanning electron microscopy, energy-dispersive X-ray spectroscopy, X-ray photoelectron spectroscopy, X-ray diffraction, and Raman spectrometry. ZnCo-MOF/GS exhibited a high specific capacitance of 695 F/g at 1.0 A/g and excellent cyclic stability with 78% retention after a 7500 cycle test in 3.0 M KOH. Furthermore, a ZnCo-MOF/GS based symmetric supercapacitor (SC) was fabricated, and this flexible device displayed a specific capacitance of 302 F/g at 1.0 A/g, an energy density of 108 W h/kg, and a power density of 5037 W/kg. Moreover, this flexible SC kept its excellent performance at severe bending conditions. We believe that our electrode with its outstanding electrochemical performance has a great potential in energy storage applications, especially for lightweight and flexible electronics.

“…The properties of hydrogels, such as high conductivity and excellent mechanical properties, are critical for their applications in energy storage devices and flexible sensors to ensure their maximum application values. − However, it is still challenging to attain flexible hydrogels that have these desirable properties at the same time. , For example, one way to improve their conductivity is to incorporate conductive fillers, such as metals, carbon-based materials, and conductive polymers, into hydrogels; − unfortunately, the addition of these conductive fillers may have a negative effect on the mechanical properties of hydrogels, such as decreased stretchability and increased stiffness . Therefore, it is highly desirable to develop effective strategies to prepare hydrogels with superior ionic conductivity while having excellent mechanical properties, such as flexibility. ,, …”

Preparation of natural polymer-based highly conductive hydrogels with tunable mechanical properties for applications in flexible electronics is still challenging. Herein, we report a facile method to prepare lignin-based Fe3+-rich, high-conductivity hydrogels via the following two-step process: (1) lignin hydrogels are prepared by cross-linking sulfonated lignin with poly(ethylene glycol) diglycidyl ether (PEGDGE) and (2) Fe3+ ions are impregnated into the lignin hydrogel by simply soaking in FeCl3. Benefiting from Fe3+ ion complexation with catechol groups and other functional groups in lignin, the resultant hydrogels exhibit unique properties, such as high conductivity (as high as 6.69 S·m–1) and excellent mechanical and hydrophobic properties. As a strain sensor, the as-prepared lignin hydrogel shows high sensitivity when detecting various human motions. With the flow of moist air, the Fe3+-rich lignin hydrogel generates an output voltage of 162.8 mV. The assembled supercapacitor of the hydrogel electrolyte demonstrates a high specific capacitance of 301.8 F·g–1, with a maximum energy density of 26.73 Wh·kg–1, a power density of 2.38 kW·kg–1, and a capacitance retention of 94.1% after 10 000 consecutive charge–discharge cycles. These results support the conclusion that lignin-based Fe3+-rich, high-conductivity hydrogels have promising applications in different fields, including sensors and supercapacitors, rendering a new platform for the value-added utilization of lignin.
