- Abstract
- We fabricated photopacternable and conductive polymer/multiwalled carbon nanotube (MWNT) composites by dispersing MWNTs with poly(4-styrenesulfonic acid) (PSS) and poly(acrylic acid) (PAA) in water PAA enables photo-cross-linking in the composite by adding ammonium dichromate, and PSS assists the dispersion of MWNTs in the composites, leading to higher conductivity Composite films OF PAA/PSS-MWNTs were characterized by conductivities of 14-210 S/cm and a work function of 4 46 eV, which Could be increased to 4 76 eV during UV photo-cross-linking By using PAA/PSS-MWNT composites as source/drain electrodes. 6,13-bis(triisopropylsilylethynyl)pentacene field-effect transistors (FET) exhibited a field-effect mobility of 0 101 +/- 0.034 cm(2)/(V S), which is 9 times higher than that of FETs fabricated with gold as source/drain electrodes (0 0 12 +/- 0 003 cm(2)/(V s))
