Transparent, Low-Electric-Resistance Nanocomposites of Self-Assembled Block Copolymers and SWNTs

A transparent PS‐b‐P4VP copolymer/SWNTs nanocomposite film is used as both source and drain electrode in a pentacene OTFT with transmittance and electricresistance values of 85% and 6000 Ω/□, respectively. The low electric resistance of the film is achieved by the selective doping of HAuCl4 in P4VP...

Zusammenfassung:A transparent PS‐b‐P4VP copolymer/SWNTs nanocomposite film is used as both source and drain electrode in a pentacene OTFT with transmittance and electricresistance values of 85% and 6000 Ω/□, respectively. The low electric resistance of the film is achieved by the selective doping of HAuCl4 in P4VP cores of the self‐assembled block copolymer micelles, which simultaneously provides sufficientstability for the SWNTs suspension.
