Miniaturized Hard Carbon Nanofiber Aerogels: From Multiscale Electromagnetic Response Manipulation to Integrated Multifunctional Absorbers

Advanced Functional Materials, Journal Year: 2024, Volume and Issue: 34(48)

Published: July 17, 2024

Abstract The multiscale structural engineering strategy presents a powerful method for tailoring the attributes of materials at various levels, enabling flexible control and manipulation their electromagnetic properties. Nonetheless, orchestrating architecture polymer‐derived carbon aerogels specifically microwave absorption poses significant challenges. Herein, aramid‐derived hard nanofiber aerogel microspheres (CNFAMs) featuring hierarchical skin‐core structure are fabricated through wet‐spinning technique, combined with reprotonation‐mediated self‐assembly carbonization processes. presence large‐scale voids between neighboring microscale porosity within themselves improves impedance matching promotes reflection scattering. distinct graphitic domains defects serve as pivotal elements conduction polarization losses, significantly impacting attenuation. By meticulously macroscale dimensions, porous architecture, nanoscale domains, optimized CNFAMs demonstrate remarkable bandwidth 9.62 GHz an ultralow filling 0.97 wt%. Additionally, implementation application‐oriented innovative integration polysilsesquioxane‐CNFAMs in host–guest is explored. This composite system brings together broadband absorption, superhydrophobicity, thermal insulation, resistance to freezing, robust tolerance harsh environments. Such multifaceted approach designed tackle growing challenges associated complex environments effectively.
