Water of aqueous PEDOT:PSS solution was successfully exchanged with ethylene glycol or ethanol solvents using ultrafiltration method. This novel solvent exchange process enables uniform and conformal nano-coating of PEDOT:PSS on hydrophobic substrates without the addition of surfactants. This process can be widely used in fabrication of various sensors or electronic devices using conducting polymers.
