Abstract/Summary The electromagnetic interference shielding effectiveness (EMI SE) and the electrical properties of linear low density polyethylene (LLDPE) modified by heat treated carbon nanofibers (Pyrograf® III PR-19) and mesophase pitch-based carbon fibers were investigated. After thermal treatment of the nanofibers to 2500°C, 20 wt% PR-19 thermal treated nanocomposites displayed a volume resistivity of ~105 Ω·cm, and EMI SE values as high as 15 dB for most of the VHF-UHF frequency range (30 MHz – 1.5 GHz). In addition, these nanocomposites retained half of the flexibility and strength as well as one-third of the ductility, relative to the pure LLDPE. EMI SE analysis indicates that absorption is the primary shielding mechanism.
