N2 - A transparent nanocomposite of a radical polymer, the poly(2,2,6,6- tetramethylpiperidine-1-oxy-4-yl methacrylate) (PTMA), and single-walled carbon nanotubes (SWNTs) display a reversible charging and discharging, allowing for full discharging in seconds. This is ascribed to the reversible electrochemical reaction of the pendant radical group in PTMA aided by both PTMA wrapping at a molecular level and the SWNT network for electrical conduction.
