Hybrid film comprised tungsten oxide and poly (3,4-ethylenedioxythiophene):polystyrene sulphonate (WO3 -PEDOT:PSS) was developed by applying one-step inkjet printing from an office inkjet printer. The WO3 nanoparticles were synthesized from commercial crystalline WO3 powder through a wet ball-milling process, which is a simple, environmentally-friendly, and cost-effective method of using water as a green solvent and low-energy milling. The WO3 –PEDOT:PSS inkjet ink was prepared by dispersing the as-milled WO3 and PEDOT:PSS in n-propanol and deionized water. The inkjet-printed WO3 -PEDOT:PSS thin films show marked improvements of cathodic electrochromism over WO3 films: the transmittance change of 20% at 550
