[0023] Take 20g of graphene powder, 10g of sodium periodate and 100mL of nitric acid solution with a mass fraction of 65% into a beaker, move the beaker into a water bath, control the temperature of the water bath to 85°C, stir and react for 60 minutes and then filter to obtain a filter residue. Wash 3 times with water to obtain a cleaned filter residue, add the cleaned filter residue, 100g of Sphagnum tenifolia and 80mL of water to a mortar and grind for 15min to obtain a mixed slurry, mix the mixed slurry, 10g of glucose, 3g of ammonium tartrate and 600mL of water Add it into the fermenter, and ferment it at 30°C for 5 days. After the fermentation, the fermentation product is obtained, and the fermentation product is moved into an oven, and dried at 120°C for 5 hours to obtain a dry product, which is mixed with 80 mL of methallyl alcohol Add it into a three-necked flask with a thermometer and a reflux device, move the three-necked flask into an oil bath, control the temperatu...

[0025]Take 25g of graphene powder, 11g of sodium periodate and 150mL of nitric acid solution with a mass fraction of 65% into a beaker, move the beaker into a water bath, control the temperature of the water bath to 90°C, stir and react for 75 minutes and then filter to obtain a filter residue. Wash 4 times with water to obtain a clean filter residue, add the clean filter residue, 150g sphagnum moss and 90mL water to a mortar and grind for 18min to obtain a mixed slurry, mix the slurry, 13g glucose, 4g ammonium tartrate and 700mL water Add it into a fermenter and ferment in a sealed container at 35°C for 5 days. After the fermentation is over, the fermentation product is obtained. The fermentation product is moved into an oven and dried at 125°C for 5 hours to obtain a dried product. The dried product is mixed with 90 mL of methallyl alcohol Add it into a three-necked flask with a thermometer and a reflux device, move the three-necked flask into an oil bath, control the tempera...
