The electrical conductivity can be significantly improved by constructing a three-dimensional conductive network through the chemical bonding of highly conductive one-dimensional AgNWs with two-dimensional GO. To achieve this, under acidic conditions and catalytic action at temperatures, the carboxyl group of mercaptoacetic acid undergoes esterification reaction with the hydroxyl group on GO. This reaction introduces a sulfhydryl group onto the surface of GO, resulting in the formation of graphene oxide bearing a sulfhydryl group, denoted as GO-SH. Subsequently, these sulfhydryl groups serve as growth sites for silver crystal species, allowing for precise control over the distribution and arrangement of AgNWs. The oriented arrangement of AgNWs enabled the successful preparation of AgNWs/ GO-SH composites with high electrical conductivity. Following this, the composites underwent comprehensive analysis of their structure and morphology using various characterization tools. The composite coatings prepared by vacuum filtration and mechanical pressing exhibited excellent electrical conductivity (2275.4 S/cm), as well as superior electromagnetic shielding properties (SE, 65.23 dB). These findings suggest promising applications in the field of electromagnetic shielding.

Optimizin the efficient light‐trapping in the photothermal conversion by enhancing localized surface plasmon resonance (LSPR) is crucial in improving light‐heat‐conversion efficiency of Ti3C2Tx MXene. However, its susceptibility to oxidation makes it prone to oxides formation, diminishing its metallic properties and significantly reducing the LSPR effect. This work synthesizes a kind of air‐stable hybrid Ti3C2Tx MXenes by a synergistic densification strategy that incorporates sulfhydryl‐bonding between organic and inorganic parts by reacting Ti3C2Tx MXene with thiocarboxylic acids. The resultant shortening of electron transport pathways, enhanced charge density, and the generation of additional electronic states around the Fermi level collectively contribute to an augmented LSPR effect. Additionally, the hybrid Ti3C2Tx MXenes also demonstrate high‐temperature resistance and reduced water interactions. These combined effects substantially elevate photothermal conversion efficiency through thiocarboxylic acids modification, reaching a photothermal evaporation rate of 1.77 kg m−2 h−1 with 94.56% efficiency in hybrid Ti3C2Tx MXenes. The approach paves the way for the design and development of a three‐in‐one strategy for photothermal conversion.
