Embodiment 1
[0021] (1) Add 0.5g of graphite oxide and 200ml of distilled water into a 250ml beaker, and disperse for 30min in an ultrasonic environment to form a uniformly dispersed graphene oxide mixture.
[0022] (2) Weigh 10ml of triethylenetetramine, place it in a 250ml three-neck flask equipped with a stirrer, thermometer, condenser and dropping funnel, add N,N-dimethylformamide and stir so that the triethylenetetramine is just Until it is completely dissolved, heat up to 60°C and slowly add a mixture of 2.3mL methyl methacrylate and 5.0mL methanol dropwise for 2 hours, continue to heat up to 100°C, and react for 8 hours to obtain a light yellow viscous Transparent amino-terminated hyperbranched polymer HBP-NH 2 Then add 5mL of the graphene oxide mixed solution and 8g NaOH prepared in step (1), and adjust the pH value to 7, continue ultrasonic dispersion for 6 hours at 100°C, cool to room temperature after distilling out methanol, add a large amount of water to make The product was ...
