NOVELTY - Preparation of surface transparent conducting thin film involves adding 0.1-0.3 pt. wt. oxidized graphite alkene powder into 30-100 pts. wt. water, stirring, obtaining oxidized graphene suspension, adding 16-24 pts. wt. sodium hydroxide and 0.17-12.4 pts. wt. metal salt to the obtained suspension, stirring uniformly, adding 0.16-0.8 pt. wt. diazene and 0.4-10 pts. wt. sodium borohydride reducing agent, reacting, filtering, obtaining graphene-metal nanocomposite suspension, spin coating the obtained graphene-metal nanocomposite suspension on a flexible substrate and drying. USE - Preparation of surface transparent conducting thin film (claimed). ADVANTAGE - The method economically provides surface transparent conducting thin film, by a simple process in a short period of time. DETAILED DESCRIPTION - Preparation of surface transparent conducting thin film involves adding 0.1-0.3 pt. wt. oxidized graphite alkene powder into 30-100 pts. wt. water, stirring, obtaining oxidized graphene suspension, adding 16-24 pts. wt. sodium hydroxide and 0.17-12.4 pts. wt. metal salt to the obtained suspension, stirring uniformly, obtaining mixed solution, adding 0.16-0.8 pt. wt. diazene and 0.4-10 pts. wt. sodium borohydride reducing agent into the obtained mixed solution, stirring uniformly, reacting at 80-90 degrees C for 1-2 hours, stirring the resultant reaction solution for 12-24 hours, obtaining graphene-metal nanocomposite liquid, filtering under vacuum, removing the excess of reducing agent and sodium hydroxide, stirring, obtaining graphene-metal nanocomposite suspension, spin coating the obtained graphene-metal nanocomposite suspension on a flexible substrate, and drying.
