We report a novel method of three-component spray-spin-spray coating to prepare uniform and dense Ag/graphene nanosheet (Ag/GNS) composite films on a surface modified polyethylene terephthalate (PET) substrate. Compared with an untreated sample, the adhesion between composite films and the substrate was significantly enhanced due to the effects of chemical etching and molecular grafting. From the results of the four-probe test, the sheet resistance of hybrid films of Ag/GNS-5 reduced by 60% compared to the pristine Ag films, which was due to the efficient deposition of GNS by spray-spin-spray coating method. Meanwhile, a variety of complex flexible patterns were successfully fabricated with the help of the masking method. This means that the method could provide an efficient and low cost way for flexible electronics production of various complex flexible metallic coatings in practice.
