Recent advancements in the electromagnetic interference shielding performance of nanostructured materials and their nanocomposites: a review

“…Dielectric materials and their composites have also been used in blocking incoming EM waves. 406–437 Lu et al 406 studied the thickness dependence variation of reflection loss against ε ′ and ε ′′ (Fig. 18(a)) and microwave absorption properties of the composites loaded with 10 wt% ZnO@MWCNTs vs. the frequency and thickness at different temperatures (Fig.…”

“…414 The average EMI SE with the buckypaper (BP)/PP–PLA–TiO 2 hybrid composite films of 90 μm thickness was found to be 40 dB at 0–3 GHz. 415 Graphene nanosheets/BaTiO 3 , 416 SiO 2 -coated Fe 3 O 4 -MWCNT, 417 MWCNT/La-doped BaTiO 3 , 418 (Bi 2 O 3 + B 2 O 3 )-doped MWCNT/BaTiO 3 , 419 NiFe 2 O 4 /BaTiO 3 , 420 Fe 3 O 4 –TiO 2 /natural rubber, 421 and MWCNT–BaTiO 3 /silica 422 also exhibited good shielding performance in the blocking of EM waves.…”

Ni@CNTs/Al2O3 Ceramic Composites with Interfacial Solder Strengthen the Segregated Network for High Toughness and Excellent Electromagnetic Interference Shielding

“…With the widespread use of electronic communication equipment, increasingly prominent electromagnetic radiation and electromagnetic interference (EMI) shielding seriously interrupts the operation of the equipment and even damages human health. − Traditional EMI shielding materials mainly include metal and conductive polymer composites (CPCs). − However, there are plenty of limitations in the use of metals due to their high density, high cost, low corrosion resistance, and poor molding processability. , Moreover, metals are prone to secondary pollution of electromagnetic waves due to higher electromagnetic wave reflectivity. , CPCs have excellent molding processability, low cost, low density, corrosion resistance, and other advantages, which are expected to partially replace traditional metal EMI shielding materials. , However, CPCs usually require a high content of conductive fillers, which deteriorates their mechanical properties and are difficult to adapt to applications in harsh environments, such as high-altitude aircraft, aerospace, manned spacecraft, and marine vehicles. , The EMI shielding materials used in these occasions should not only have excellent EMI shielding performance, but also sufficient mechanical properties and excellent oxidation resistance. , Therefore, ceramic-based composites containing conductive fillers have great potential to be the next-generation EMI shielding materials. , …”
