主　　题：SWCNT/RuO2/PIn nanocomposite supercapacitor 

摘      要：A ternary single-walled carbon nanotubes/RuO2/polyindole(SWCNT/RuO2/PIn)nanocomposite was fabricated by the oxidation polymerization of indole on the prefabricated SWCNT/RuO2 binary *** nanocomposite was measured by FTIR,XRD,SEM,TEM,EDS and XPS,together with the electrochemical *** electrochemical results demonstrated that the symmetric supercapacitor used SWCNT/RuO2/PIn as electrodes presented 95%retention rate after 10000 cycles,superior capacitive performance of1203 F·g^-1 at1 A·g^-1,and high energy density of 33 w h·kg^-1 at 5000 W·kg^-*** high capacitance performance of SWCNT/RuO2/PIn nanocomposite was mainly ascribed to the beneficial cooperation effect among *** indicated that the SWCNT/RuO2/PIn nanocomposite would be a good candidate for high-performance supercapacitors.
