Abstract

Conducting poly(3,4-ethylenedioxythiophene):poly(styrene-4-sulfonate) (PEDOT:PSS) containing hydroxyl surface rich SiO ₂ nanoparticles were investigated. Rearrangement and bonding of PEDOT:PSS were affected by the content of SiO ₂ nanoparticles, which resulted in the modification of an electronic band structure and electrical characteristics. A slight decrease in work function and a shift of the highly occupied molecular orbital edge to the Fermi level were induced by SiO ₂ nanoparticle addition. The current path was also tuned by SiO ₂ nanoparticles and resistance of the composite film was diminished. SiO ₂ nanoparticles affect electrostatic bonding between PEDOT:PSS and doping of PEDOT as well as increase the packing density of PEDOT:PSS.
