| Abstract Scope |
Carbon nanotube thin films are very important for many applications such as radar absorbing materials (RAM), electromagnetic interference shielding (EMI), supercapacitors and lithium-ion battery (LIB). The thickness of individual buckypaper sheet, produced by the film casting technique, often falls within the range of 40-100 μm. This work presents the efforts made in producing exceptionally thick buckypapers by enhancing the film casting technique, with the aim of achieving a thickness exceeding 400 µm. The mechanical and electrical properties of the thick buckypaper is studied. The measurement of EMI Shielding Efficiency (EMI SE) was conducted to determine the corresponding parameters of electromagnetic wave absorption. The newly developed buckypaper, with its notable thickness of 400 μm, achieved an exceptional electromagnetic interference shielding efficiency (EMI SE) of 86.7 dB within the 8.2-12.4 GHz frequency range. This EMI SE is a substantial 3.6-fold increase over traditional CNT buckypaper, illustrating a major leap in shielding capabilities. |
