Two carbon nanotubes (CNTs) coatings and their electromagnetic interference shielding effectiveness (SE) have been investigated. The CNTs coatings with aspect ratio of 500, 500-1000 are added into coatings as fillers. The SE of two types of coatings containing 8-10% CNTs with thickness 0.7 mm coating is up to 16.5 dB, indicating CNTs coating could be a promising material as electromagnetic shielding materials for industrial applications. The structure and usage of CNTs, the thickness of coatings, SE measurement results are presented and discussed.
