A Comprehensive Study on EMI Shielding Performance of Carbon Nanomaterials-Embedded CFRP or GFRP Composites

“…Recently, polymeric composites incorporating carbon-based nanomaterials (CNMs) for EMI shielding have been highlighted [ 10 , 11 , 12 ]. CNMs with excellent electrical conductivity and outstanding EM wave-shielding properties are regarded as prominent candidates for fabricating EMI shielding composites [ 10 , 11 , 12 ].…”

“…CNMs with excellent electrical conductivity and outstanding EM wave-shielding properties are regarded as prominent candidates for fabricating EMI shielding composites [ 10 , 11 , 12 ]. Thus, many researchers have attempted to utilize CNM-embedded polymeric composites as lightweight EMI shielding composites to mitigate the drawbacks of conventional EMI shielding composites [ 10 , 11 , 12 ]. Yang et al [ 10 ] developed carbon nanotubes (CNTs) and graphene-embedded silicon-based composites for EMI shielding, where the fabricated composites exhibited shielding effectiveness of 32.1 dB in the frequency range of 8.2–12.4 GHz, which is called the X-band.…”

“…Zhao et al [ 11 ] fabricated hybrid sponge-type EMI shielding composites using reduced graphene oxide (rGO) and CNTs, achieving approximately 35 dB of shielding effectiveness in the X-band. Jang et al [ 12 ] manufactured CNT-embedded polymeric composites with a shielding effectiveness of approximately 22 dB at a frequency of 8 GHz. Qi et al [ 13 ] examined the EMI shielding effectiveness of a polyvinylidene fluoride (PVDF)-based sandwich structure consisting of graphite nanoplatelets (GNPs), Ni, and CNTs [ 13 ].…”

Enhanced Microwave-Absorbing Property of Honeycomb Sandwich Structure with a Significant Interface Effect

“…At the same time, the high flexural strength/mass ratio and strong anti-instability ability of AHSS determine that it plays an important structural and functional integration role of "wave-transmitting spear and stealth shield" on stealth aircraft [13][14][15]. In addition to the mesoscopic scale design of AHSS, the microstructure design of conductive fillers can also serve as an important means to improve electromagnetic absorption and shielding capabilities [16,17].…”
