Fabrication of PEDOT/PSS-ZnO nanowire by self-assembly method under vacuum condition

Poly(3,4-ethylenedioxythiophene) (PEDOT) has at- tracted much attention due to its high conductivity, excel- lent environmental stability and chemical processabil- ity1,2]. PEDOT/PSS dispersion is a water-soluble system using poly(styrene sulfonic acid) (PSS) as the doping counterion during polymerization. The inclusion of PSS results in better solubility and processability to the PE- DOT/PSS aqueous dispersion3, 4]. Recently, synthesis of one-dimensional (1D) multifunc- tional co…

Fabrication of PEDOT/PSS-ZnO nanowire by self-assembly method under vacuum condition

In this paper, cable-like PEDOT/PSS-ZnO nanowires are successfully fabricated under vacuum condition by self-assembly of the PEDOT/PSS-ZnO composite initially prepared via sol-gel method. Characterized by TEM and EDX, the nanowire is found to have a polycrystalline ZnO inner core that is sheathed by the PEDOT/PSS blends and the nanowire has an outer diameter of ca. 100 nm. The results also indicate that the morphology of PEDOT/PSS-ZnO nanocomposite is greatly influenced by external vacuum condition and aging time. The feasible and simple approach that we have developed provides a new strategy for the synthesis of novel one-dimensional nanocomposites.
