Flexible transparent conductive films were made on PET substrates by spin and blade coating,using graphene sheets dispersed in PEDOT:PSS solution.Ultrasonic substrate vibration was used to improve microstructure and properties of the films.Comparing to the pristine PEDOT:PSS film,the sheet resistance is 3 to 4 orders of magnitude lower with the addition of graphene.The conductivity and reproducibility of the film are improved for two-layer films comparing to one-layer films,with a reduction in transparency.Films prepared with substrate vibration showed lower sheet resistance for one-layer films,as the size of dewetting areas is reduced.In addition,large-area flexible films with desirable conductivity and transmittance were successfully fabricated by blade coating,which is promising,as the process is low-cost,scalable and compatible with roll-to-roll manufacturing.
