The following article appeared in APPLIED PHYSICS LETTERS. 95(23):233104 (2009) and may be found at https://doi.org/10.1063/1.3271768 ., Freestanding, thin, and bendable electrodes for supercapacitors are fabricated by filtering DNA-dispersed double walled carbon nanotubes (DWNTs) into a thin film and thermally treating the film in argon. We found that DNA has the ability to disperse the strongly bundled DWNTs and is converted to phosphorus-enriched carbons, which give rise to strong redox peaks at around 0.4 V. The combination of the large capacitance from the DNA-derived carbons and the high electrical conductivity of carbon nanotubes allow DWNT/DNA films to be used as a potential electrode material for supercapacitors., Article, APPLIED PHYSICS LETTERS. 95(23):233104 (2009)
