Multifunctional applications including efficient microwave absorption and electromagnetic interference (EMI) shielding as well excellent Li-ion storage are rarely achieved in a single material. Herein, multifunctional nanocrystalline-assembled porous hierarchical NiO@NiFe2 O4 /reduced graphene oxide (rGO) heterostructure integrating absorption, EMI shielding, functions is fabricated tailored to develop high-performance energy conversion devices. Owing its structural compositional advantages, the optimized /15rGO achieves minimum reflection loss of -55 dB with matching thickness 2.3 mm, effective bandwidth up 6.4 GHz. The effectiveness reaches 8.69 dB. exhibits high initial discharge specific capacity 1813.92 mAh g-1 , which 1218.6 after 289 cycles remains at 784.32 500 0.1 A . In addition, demonstrates long cycling stability current densities. This study provides an insight into design advanced materials devices innovative method solving environmental problems.

Three-dimensional (3D) elastic aerogels enable diverse applications but are usually restricted by their low thermal and electrical transfer efficiency. Here, we demonstrate a strategy for fabricating the highly thermally electrically conductive using hybrid carbon/ceramic structural units made of hexagonal boron nitride nanoribbons (BNNRs) with in situ-grown orthogonally structured graphene (OSG). High-aspect-ratio BNNRs first interconnected into 3D skeleton, which horizontal layers OSG provide additional hyperchannels electron phonon conduction, vertical sheets greatly improve surface roughness charge polarization ability entire skeleton. The resulting OSG/BNNR aerogel exhibits very high conductivity (up to 7.84 W m-1 K-1 340 S m-1, respectively) at density 45.8 mg cm-3, should prove be vastly advantageous as compared reported carbonic and/or ceramic aerogels. Moreover, possesses integrated properties wide temperature-invariant superelasticity (from -196 600 °C), low-voltage-driven Joule heating 42-134 °C 1-4 V), strong hydrophobicity (contact angel up 156.1°), powerful broadband electromagnetic interference (EMI) shielding effectiveness (reaching 70.9 dB 2 mm thickness), all can maintain well under repeated mechanical deformations long-term immersion acid or alkali solution. Using these extraordinary comprehensive properties, great potential wearable electronics regulating body temperature, proofing water pollution, removing ice, protecting human health against EMI.
