DETAILED DESCRIPTION - A graphene transparent conductive film preparing method involves preparing graphene oxide-alkene, followed by surface modifying graphene oxide-alkene in organic solvent using silane coupling agent. The surface modified graphene oxide-alkene is ultrasonically dispersed in organic solvent, mixing terephthalic acid, ethylene glycol, catalyst and stabilizer, vacuum condensation heating and discharging to obtain modified polyester polyethylene terephthalate film. The modified polyester polyethylene terephthalate film is dried, extruded and stretched by two-way stretching to obtain graphene modified polyethylene terephthalate film, followed by preparing a composite electric conductive coating by ultrasonically mixing nano-metal aqueous solution, graphene-oxide and antimony tin oxide/indium tin oxide solution with weight ratio of 1-10:1-10:1-10 to obtain mixed liquid, adding 0.1-5 pts. wt. dispersing agent to 100 pts. wt. mixed liquid, adding 1-10 pts. wt. polymer resin having uniform molecule weight (Mn) of less than 10000, ultrasonically and continuously mixing for 10-60 minutes and performing centrifugal separation to obtain the supernatant as composite electric conductive coating. The composite electric conductive coating is coated with graphene modified polyethylene terephthalate film to obtain graphene transparent conductive film. An INDEPENDENT CLAIM is also included for a graphene transparent conductive film prepared by the method.
