Electromagnetic interference (EMI) shielding effectiveness (SE) of various types of single-walled carbon nanotube (SWCNT) films were investigated. By systematically changing M/S ratios of the films, significant change in EMI SE values were observed. Different shielding mechanisms were discovered from the films of M/S ratio at their extreme, namely purely semiconducting- (s-) and metallic (m-) SWCNT films. These characteristics were explored by density gradient ultracentrifugation (DGU), UV-Vis-NIR spectroscopy, EMI SE measurement. This work is expected to be applied to various shielding materials for future electronic devices.
