Compared to conductive carbon black and multi-walled carbon nanotubes, single-walled carbon nanotubes (SWCNTs) have a higher aspect ratio, superior electrical conductivity, flexibility, and mechanical properties, making them an ideal additive for composite materials. By adding only a minimal amount of SWCNTs, you can significantly enhance the strength, toughness, electrical conductivity, and thermal conductivity of materials like plastics, rubber, and coatings without altering their original color, while also reducing the risk of decarburization. Consequently, SWCNTs have broad application prospects in fields such as antistatic plastics/rubber, lightweight, high-strength composites, optical films, electromagnetic shielding materials, and functional coatings. For example, they can be used to manufacture lightweight yet strong structural parts for aerospace and robotics, conductive structural components for electric vehicles, and to develop new materials with electromagnetic shielding functions.
