Carbon quantum dots modified polypyrrole/titania (CQDs-PPy/TiO 2 ) nanotube hybrid was designed as supercapacitor electrode material for an energy storage. CQDs-PPy/TiO 2 was prepared by incorporating CQDs-hybridized PPy into well-aligned titania nanotube array. CQDs-PPy/TiO 2 exhibited a highly-ordered heterogeneous coaxial nanotube structure. CQDs hybridizing modification could well improve the electrical conductivity of PPy. The charge transfer resistance decreased from 22.4 mΩ cm −2 to 9.3 mΩ cm −2 and the ohmic resistance decreased from 0.817 for to 0.154 Ω cm −2 when PPy/TiO 2 was converted into CQDs-PPy/TiO 2 nanotube hybrid. The specific capacitance was accordingly enhanced from 482 F g −1 (or 161 mF cm -2 ) for PPy/TiO 2 to 849 F g −1 (or 212 mF cm -2 ) for CQDs-PPy/TiO 2 at a current density of 0.5 A g −1 . The capacitance retention was slightly increased from 78.5% to 89.3% after 2000 cycles at high current density of 20 A g −1 .The effective incorporation CQDs into PPy could simultaneously increase electrochemical capacitance and cycle stability of PPy, leading to a superior electrochemical performance. A flexible solid-state supercapacitor based on CQDs-PPy nanohybrid exhibited the stable capacitive performance at both planar and bending state. CQDs-hybridized PPy presented the promising application as supercapacitor electrode material for energy storage.
