Core Viewpoint - The research and development of electromagnetic wave (EMW) absorbing materials are increasingly important due to the widespread application of high-frequency electromagnetic technology. High entropy materials (HEM) have emerged as a promising new class of materials, but their absorption efficiency and matching performance need improvement. The combination of metal nanoparticles with carbon-based materials can enhance EMW absorption performance, with electrospun porous carbon nanofibers (CNF) being a key focus area [1][8]. Group 1 - The team from Anhui University successfully developed a honeycomb-like porous CNF/HEA composite material using electrospinning and Joule heating methods. This composite achieves a minimum reflection loss of -65.8 dB with only 2 wt% filler and a wide absorption bandwidth of 7.68 GHz, setting new records in both CNF and HEA absorbers [2]. - The synergistic effect of the honeycomb structure of CNF and HEA significantly enhances EMW absorption performance, providing a lightweight and wideband absorption material option for EMW applications [2]. - The research findings were published in the journal "ACS Nano" under the title "Joule-Heating-Driven Synthesis of a Honeycomb-Like Porous Carbon Nanofiber/High Entropy Alloy Composite as an Ultralightweight Electromagnetic Wave Absorber" [2]. Group 2 - The increasing attention on efficient EMW absorbing materials is driven by the extensive application of electromagnetic technology across various fields. Traditional metal-based absorbers have high magnetic loss and strong absorption capabilities but are hindered by high density and low stability [8]. - Carbon-based materials, while lightweight, have high dielectric constants and poor impedance matching performance. Combining carbon-based materials with magnetic materials through optimized composition and structural design is a strategy to enhance EMW absorption performance [8]. - Advanced characterization techniques and DFT theoretical calculations have been employed to conduct detailed studies on the loss mechanisms at the atomic and molecular levels [8].
