Carbon nanotubes  have proven to be an excellent additive to impart electrical conductivity in plastics. Their high aspect ratio, about 1000:1 imparts electrical conductivity at lower loadings, compared to conventional additive materials such as carbon black, chopped carbon fiber, or stainless steel fiber.
Carbon nanotubes are the strongest and stiffest materials yet discovered in terms of tensile strength and elastic modulus respectively
Current earning capacity of copper interconnects is being severely limited due to their increasing resistivity with scaling and reliability constraints. Metallic carbon nanotubes (CNT) are promising candidates that can potentially address the challenges faced by copper and thereby extend the lifetime of on-chip electrical interconnects.
