Abstract
We prepared nanocomposite inks of poly(3,4-ethylenedioxythiophene)–poly(styrenesulfonate)(PEDOT–PSS) filled with single-walled carbon nanotubes (SWNTs) purified by acidictreatment, carboxylated by chemical oxidation and carboxyl-functionalized nanotubes physicallymodified with a natural gum, gum arabic. Inkjet printing of line patterns with a feature size of100 µm width and lengths ranging from 1 to 5 cm was performed on glass substrates with apiezoelectric inkjet printer. The carboxyl-functionalized SWNT-based compositedemonstrated a significant decrease (fourfold) of electrical resistance for the linepatterns compared to that with a purified CNT-based composite due to improveddispersability of nanotubes in the polymer matrix. The use of gum arabic for thedispersion of carboxyl-functionalized nanotubes demonstrated a further drasticdecrease (18-fold) of the resistance compared with a purified CNT-based compositeowing to the formation of an extended continuous network within the line pattern.The inkjet-printed conductive patterns can be applied in various fields, such asflexible high speed transistors, high efficiency solar cells and transparent electrodes.
