In this study, a dual conductive network of nickel-coated carbon fiber woven fabrics (Ni-CFWF) was presented for indirect and direct lightning strike protection (LSP) of carbon fiber reinforced polymer (CFRP) composites. The Ni-CFWF prepared by electroless plating was bonded to the top surface of a CFRP composite. Excellent electromagnetic interference shielding effectiveness of Ni-CFWF/CFRP composite was achieved with a value of 92.87 dB in the frequency range 8.2-12.4 GHz, 189.22% greater than that of the pristine CFRP composite. Moreover, the prepared Ni-CFWF also exhibited a good direct lightning strike (LS) protection performance. The maximum LS damage depth and area of the Ni-CFWF/CFRP composites were reduced by 21.59% and 6.11% under a simulated lightning current with the peak of 100 kA, respectively. Correspondingly, the residual strength of the Ni-CFWF/CFRP composites was maintained at 92.65% after LS, demonstrated the LSP effectiveness. Our work provides an effective strategy for the design of a protective system that considers both indirect and direct LSP.

“…Once the incident electromagnetic wave (EMW) strikes the surface of BRNGs, a portion of the EMW is immediately reflected at the air-specimen interface because of the impedance mismatch . Meanwhile, the EMW will interact with Ni nanoparticles to form multiple magnetic losses containing the natural resonance, eddy current loss, and magnetic-coupling effects, resulting in strong magnetic loss that further dissipates the EMW . In addition, multiple reflections provide the opportunity for repeated absorption electromagnetic microwaves.…”

With the rapid development of information technology, the application scenarios of electromagnetic interference (EMI) shielding materials are more diversified. It is difficult for traditional EMI shielding materials to possess low density, high EMI shielding performance, strength, and flexibility in extreme environments such as oxidation/deformation/salt/alkali/high temperature/impact energy/bacteria. Herein, reduced graphene oxide nanosheets (RGO) and Ni nanoparticles were subsequently coated on glass fabrics (GFs) modified with bovine serum albumin (BSA) by adhesion, electrostatic adsorption, and metallization. A 1D glass fiber modified with BSA was used as a flexible substrate, while 2D RGO nanosheets that adhered on the surface of the abovementioned fibers provide a large specific surface area and structural defects and further promote the anchoring of 0D Ni nanoparticles. 2D/1D/0D construction shows an excellent synergistic effect, which promotes the formation of a firm conductive network and lays the foundation for multifunction. EMI shielding efficiency (EMI SE) of the prepared BSA/RGO/Ni-GFs (BRNGs) ranges from 52 to 72 dB in the range of 2−18 GHz. 2D/1D/0D BRNGs with flexibility also show fantastic binding fastness (EMI SE maintaining 89.1 and 86.0% after repeated bending 400 cycles at 90°and ultrasonic damage for 1 h, respectively) and chemical stability (EMI SE remaining 80.2, 95.3, and 92.6% after 200 °C oxidation for 12 h and salt/alkali corrosion for 12 h). In addition, Joule heating, photothermal properties, contact angle, heat dissipation, and mechanical and antibacterial properties of BRNGs were tested. The integration of excellent energy conversion, heat dissipation, and mechanical strength further improves the practicability of the electromagnetic shielding material. Antibacterial and hydrophobic properties of BRNGs are also beneficial to prolong the service life. This study provides a new idea for the design of multifunctional electromagnetic shielding composites.

Flexible and robust multifunctional electromagnetic interference (EMI) shielding materials are playing an increasingly important role in areas of aerospace, electronic communication, artificial intelligence, and wearable electronic devices. Herein, the magnetic and conductive Ti3C2T x /(ANF@FeNi) EMI shielding composite films are fabricated via in situ growth and vacuum‐assisted filtration methods. The introduction of magnetic FeNi nanoparticles can effectively enhance the electromagnetic recombination losses, leading to improved EMI shielding effectiveness (EMI SE) of the composite films. The obtained Ti3C2T x /(ANF@FeNi) composite films show excellent EMI shielding and electrothermal conversion performances. When the mass fraction of Ti3C2T x and FeNi fillers is 60 wt% and their mass ratio is 4:1, the EMI SE of the composite films (50 μm) reaches 60.7 dB in the X‐band (8.2–12.4 GHz). When a low voltage of 3 V is applied, the surface heating temperature of the composite films quickly reaches 111.2 °C. Moreover, the composite films possess satisfied long‐term heating stability under the constant applied voltage. In addition, the composite films exhibit excellent thermal conductivity and mechanical properties. The thermal conductivity (λ) and thermal diffusivity (α) reach 4.72 W m−1 K−1 and 4.36 mm2 s−1, respectively, and the tensile strength and tensile modulus reach 113.4 MPa and 3.1 GPa, respectively.
