Polyaniline can be widely applied in the field of supercapacitors, secondary batteries, sensors and et al. due to the numerous advantages such as low cost, easy preparation, good stability, unique doping behaviors and electrochemical performance. Aiming at the difficulty in adjusting the structure of polyaniline composites prepared by in-situ polymerization of aniline monomer, in this project, we propose to systematical research on the interaction between carbon nanotubes and polyaniline molecular chains with different electronic and molecular structures. Based on the molecular chain restriction behavior of polyaniline on the surface of carbon nanotubes, a series of polyaniline composites with different components and structures will be designed and constructed. Furthermore, the structure-activity relationship of polyaniline/carbon nanotube composites and polyaniline/carbon nanotube/sulfur composites will be established. The controllable preparation theory and related mechanism of polyaniline composites will be further clarified, providing theoretical basis and key technologies for preparing high-performance electrode materials for supercapacitors and lithium-sulfur batteries. This work meets the requirements of the national medium to long-range program for scientific and technological development, as well as possess important scientific significance and practical value.
