{
    "protocol": "A simple and low-cost method for preparing high performance GO coating on glass substrate is described. The synthesis involves using graphene oxide (GO) which has various oxygen-containing functional groups that contribute to its hydrophilic properties. The process aims to achieve high optical transmittance and superhydrophilic characteristics without the complex steps of reduction and bridization commonly associated with other preparation methods.GO was prepared using the modified Hummers method. To remove the oxidant and other inorganic impurities, the GO slurry was washed with deionized water by repeated vacuum filtration through a 100 nm cellulose acetate membrane. Then the suspension was centrifuged at 13,000 rpm for 80 minutes, and the supernatant was kept. Finally, the supernatant was diluted with deionized water to a total volume of 200 ml in a 500 ml flask to make a homogeneous GO suspension at 0.2 mg/l for storage.GO coating was deposited on the glass substrate by a spin coating process. Initially, the substrate was ultrasonically cleaned in ethanol and deionized water. After cleaning, the substrate was dried at 60°C for 1h. Then, the above-mentioned GO suspension was dropped on the glass substrate and spun at 500rpm for 10s and dried at 60°C for 3h to enhance the mechanical property of the coating. The other side of the glass substrate was operated by the same procedure. Finally, both sides of the glass substrate were covered with GO coating."
