Abstract In this study, the nanocables were prepared by the supramolecular self-assembly interaction between polyaniline (PANI) and linear carboxymethyl-β-cyclodextrin polymer functionalized carbon nanotubes (L-CM-β-CD-P-CNTs). Its morphological, thermal, structural, and electrochemical properties were analyzed by using different instrumental techniques. As expected, the PANI/L-CM-β-CD-P-CNTs supramolecular nanocables exhibited excellent electrochemical performance and cycling stability. More importantly, the specific capacitance (SC) values for PANI/L-CM-β-CD-P-CNTs reached 996 F g−1 at a current density of 1 A g−1. In addition, the PANI/L-CM-β-CD-P-CNTs supramolecular nanocables exhibited 90 % capacitance retention after 15,000 charge-discharge cycles.
