Conducting Ag/oligothiophene complex pastes through a simple quenching/chelation method

Abstract

This paper describes a simple and environmentally friendly approach—a facile, one-pot, quenching/chelation method—for the fabrication of a silver paste in the form of Ag/oligothiophene complex composites. These Ag/oligothiophene complex composites possess excellent conductivities of 1.8 × 10⁴ S cm⁻¹ in the bulk state and 6.08 × 10² S cm⁻¹ in the form of thin films. We have used X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), transmission electron microscopy (TEM), and scanning electron microscopy (SEM) to characterize the microstructures of these novel Ag/oligothiophene complex composites.
