The development of wearable multifunctional electromagnetic protective fabrics with multifunctional, low cost, and high efficiency remains a challenge. Here, inspired by the unique flower branch shape "Thunberg's meadowsweet" in nature, nanofibrous composite membrane hierarchical structure was constructed. Integrating sophisticated 0D@2D@1D structures multiple heterointerfaces can fully unleash application potential membrane. targeted induction method used to precisely regulate formation site morphology metal-organic framework precursor, intelligently integrate heterostructures enhance dielectric polarization, which improves impedance matching loss mechanisms wave absorbing materials. Due synergistic enhancement electrospinning-derived carbon nanofiber "stems", MOF-derived nanosheet "petals" transition metal selenide nano-particle "stamens", CoxSey/NiSe@CNSs@CNFs (CNCC) obtains minimum reflection value (RLmin) -68.40 dB at 2.6 mm maximum effective absorption bandwidth (EAB) 8.88 GHz thin thickness 2.0 filling amount only 5 wt%. In addition, multi-component heterostructure endow fibrous excellent flexibility, water resistance, thermal management, other properties. This work provides perspectives for precise design rational fabrics.

The rational design of lightweight, broad-band, and high-performance microwave absorbers is urgently required for addressing electromagnetic pollution issue. Metal single atoms (M-SAs) receive considerable interest in the field absorption due to unique electronic structures M-SAs. However, simultaneous engineering morphology structure M-SAs based remains challenging. Herein, a template-assisted method utilized fabricate isolated Co-SAs on N-doped hollow carbon spheres (NHCS@Co-SAs) absorption. combination atomically dispersed Co sites supports endows NHCS@Co-SAs with excellent properties. Typically, at an ultralow filler content 8 wt%, minimum reflection loss effective bandwidth are up -44.96 dB 5.25 GHz, respectively, while absorbing thickness only 2 mm. Theoretical calculations experimental results indicate that impedance matching characteristic dielectric NHCSs can be tuned via introduction M-SAs, which responsible properties NHCS@Co-SAs. This work provides atomic-level insight into relationship between states their developing advanced absorbers.
