Embodiment 1
[0049] Weigh 1.60g of acetyl triethyl citrate, 0.75g of aminobutanol, (the molar ratio is 1:1.7), mix thoroughly, place in a 20mL glass microwave reaction tube, and control the reaction under 2.45GHz, 700W microwave irradiation conditions React at a temperature of 300°C for 3 minutes to obtain a crude product of amphiphilic graphene quantum dots. After cooling to room temperature, 4 mL of ethanol was added to the microwave reaction tube, and the product was completely dispersed by ultrasonic treatment. The ethanol dispersion of the prepared graphene quantum dots was transferred to a 50mL centrifuge tube, and 20mL of ethyl acetate was added therein to precipitate the graphene quantum dots from the ethanol-ethyl acetate mixed solution. The obtained product was centrifuged and precipitated, and the supernatant was removed by decanting, and 4 mL of ethanol was added to the precipitate, and the precipitate was dispersed in ethanol again by ultrasonic dispersion. The precipitate wa...
