- Abstract
- EMI shielding films made from carbon nanotube grafted with organic polymers at a low cost have been developed. MWCNTs exhibit desirable electrical properties for EMI shielding films. In this study, PEG was employed by urethane bonding to increase the processability and dispersibility of the MWCNTs. The molecular weight of PEG was 200 and 2000, and their EMI shielding films were fabricated by addition of UV-curing photoinitiator. The EMI shielding property was measured, and they show proper EMI reflectance and shielding effectiveness. Especially, when 4.0 wt% of MWCNTs were added to PEG with a molecular weight of 200 g/mol, it exhibited the maximum EMI SE value was -22.9 dB at 4.14 GHz, while the average EMI SE value which was -20.53 dB.
