Abstract
Helical CNT possesses excellent mechanical, electrical, and thermal properties as well as high chemical stability and large aspect ratio similar to ordinary CNT. It also has unique chiral structure, which is beneficial to enhancing the dielectric properties of CNT. Therefore, as a nanoscale metamaterial, helical CNT shows great potential for improving/modifying the properties/performances of cement-based composites. The cement-based nanocomposites with helical CNT have enhanced static and dynamic mechanical properties due to the helical CNT modification effect on the structures of cement-based composites. Especially, they exhibit excellent electromagnetic shielding and absorption properties because of the unique chiral structures as well as extensive distribution of helical CNT, thus presenting excellent application prospects in electromagnetic protection and control of military, nuclear power plant and extraterrestrial infrastructures.
