Carbon nanotube buckypaper and buckypaper/polypropylene composites for high shielding effectiveness and absorption-dominated shielding material

Buckypaper (BP) was prepared as efficient electromagnetic interference (EMI) shielding materials in X-band (8.2–12.4 GHz). The EMI shielding effectiveness (SE) of 31.2 dB and a high specific SE of 19850 dB cm2/g have been realized by BP of 35 μm thick. Notably, the absorption-dominated SE above 100 dB can be achieved by constructing multilayer structure or sandwich structure using BP and polypropylene sheet. For multilayer structure, the...
