Abstract
We investigated the tailored electromagnetic interference (EMI) shielding of polyester-matrix composites consisting of carbon nanotube- and exfoliated graphite nanoplatelet-coated glass fiber reinforcement. The effects of various combinations of material parameters, including carbon nanotube length, exfoliated graphite nanoplatelet size, and amount of carbon nanomaterials coated per unit area, on the EMI shielding effectiveness were studied. Due to their capability to form conductive networks more efficiently, high-aspect-ratio nanomaterials exhibited better EMI shielding, ranging from 35.3 dB to 56.8 dB. For all the composites fabricated and tested, the EMI shielding effectiveness decreased with increasing frequency.
