One-Pot Synthesis of UV-Curable Au/PEDOT Conductive Ink by Using Amphiphilic Polymer PSMH as Templates

Abstract:

In this paper, we report a one-pot method to prepare a new type of UV-curable Au/PEDOT nanocomposite used in printed electronics, which use an amphiphilic polymer polystyrenesulfonate-alt-[maleic anhydride-g-(2-hydroxy-ethyl-methacrylate)] (PSMH) as a conductive ink. The synthesis included the reduction of chloroauric acid using EDOT (3, 4-Ethylenedioxythiophene).PSMH acted a dopant for PEDOT and a stabilizer of Au nanoparticles due to the ligand exchange between chloroauric acid and carboxylate group. The carbon-carbon double bonds have been introduced into this ink with UV-curable property to enhance the water resistance of this nanocomposite before inkjet-printing. The particle size of this nanocomposite is above 200 nm while the gold particles size is above 3~10 nm. This UV-curable Au/PEDOT nanocomposite can be used as a conductive ink for inkjet printing.
