Abstract Hydrogen‐bonded organic frameworks (HOFs) and metal–organic (MOFs) emerge as promising materials for electromagnetic wave (EMW) absorption, due to their high specific surface area readily modifiable characteristics. In this study, 1D magnetic nickel‐carbon matrix nanotube composites (Ni‐HMCNTs) from a mixture of HOFs MOFs (Ni‐HMNTs) EMW absorption are synthesized. The Ni‐HMNTs achieved via one‐step method involving single‐pot solvothermal reaction among melamine, trimeric acid, nickel nitrate. This process involves HOF‐to‐MOF transformation, characterized by the penetration Ni ions into HOF structure competitive coordination reaction, resulting in hollow Ni‐HMNTs. Subsequent calcination yields Ni‐HMCNTs optimized absorption. Remarkably, with filling degree only 10 wt%, 1.2 Ni‐HMCNTs‐700 (heat‐treated at 700 °C) exhibits exceptional properties, minimum reflection loss ( RL min ) value −50.4 dB maximum effective bandwidth (EAB) 7.32 GHz (10.64–17.96 GHz). These findings pave way further exploration magnetically modified HOFs/MOFs applications.

Abstract Electromagnetic interference (EMI) significantly affects the performance and reliability of electronic devices. Although current metallic shielding materials are effective, they have drawbacks such as high density, limited flexibility, poor corrosion resistance that limit their wider application in modern electronics. This study investigates EMI properties 3D‐printed conductive structures made from polylactic acid (PLA) infused with 0D carbon black (CB) 1D nanotube (CNT) fillers. demonstrates CNT/PLA composites exhibit superior effectiveness (SE), achieving 43 dB at 10 GHz, compared to 22 for CB/PLA structures. Further, coating polyaniline (PANI) electrodeposition onto improves SE 54.5 GHz. strategy allows fine control PANI loading relevant tuning SE. Additionally, PLA‐based offer several advantages, including lightweight construction enhanced resistance, positioning them a sustainable alternative traditional metal‐based materials. These findings indicate can be substantially improved through low‐cost straightforward electrodeposition, enabling production customized performance. novel fabrication method offers promising potential developing advanced solutions

Abstract Highly integrated multifunctional materials are crucial for the development of next‐generation aircraft and electronic communication devices. In this study, a novel ultra‐thin MXene film with high optical transparency broad multispectral electromagnetic responses is first fabricated using scanning centrifugal casting (SCC) technique. The MXene‐coated PET films significantly integrate transparency, UV‐adsorption, infrared (IR) stealth, shielding from gigahertz (GHz) to terahertz (THz) frequencies together address diverse demands applications. all‐in‐one flexible exhibit excellent optoelectronic properties (sheet resistance 163 Ω sq −1 at 82% figure merit 10.88), outstanding IR stealth (IR emissivity below 55%), ultra‐broad performance (shielding effectiveness over 10 dB across GHz THz frequencies). This remarkable attributed intrinsic multifunctionality MXene, thickness, horizontal alignment nanosheets, strong interfacial interactions achieved during SCC process. These great potential applications in windows, wearable electronics, technology.
