This work presents a simple process for the development of flexible acetone gas sensors based on zinc oxide/graphene/poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate). The were prepared by inkjet printing, which was followed metal sparking involving different times. successful decoration ZnO nanoparticles (average size ~19.0 nm) surface graphene–PEDOT:PSS hybrid ink determined characterizations, including Raman spectroscopy, Fourier transform infrared field-emission transmission electron microscopy, X-ray photoelectron and diffractometry. nanoparticle-decorated with time 2 min exhibited highest response 71.9% at 10 ppm acetone, above those samples treated other times undecorated control. In addition, optimal sensor revealed high selectivity over several kinds gases, such as ammonia, toluene, dimethylformamide, ethanol, methanol, benzene, room temperature. also low limit detection (0.4 ppm), sensitivity (6.18 ppm−1), stability (5-week long-term) to acetone. recovery found be 4.6 4.2 min, respectively. acetone-sensing mechanism attributed formation p-n heterojunctions, responsible significantly enhanced sensitivity.
