dc.description.abstract | An experiment was conducted to show that graphene oxide (GO) nanosheets can be readily reduced by dopamine with simultaneous capping by polydopamine to provide a versatile platform for covalent grafting of functional polymer brushes. Natural graphite flakes, dopamine hydrochloride O-[2-(3- mercaptopropionylamino) ethyl]-O0-methylpoly(ethylene glycol) (thiol-terminated PEG) and O-(2-aminoethyl)-O0-[2-(bocamino ethyl]poly(ethylene glycol) (amino-terminated PEG) were used. Graphite and NaNO3 were mixed with concentrated H2SO4 in a 250 mL flask at 0°C. The temperature was kept at 5°C, and the mixture was stirred for 2 h. After that, 7.3 g of KMnO4 was added in small portions to prevent temperature rise in excess of 20°C. Then, the temperature of the reaction mixture was raised to 35±2°C, and the mixture was stirred for 30 min. Fourier transform infrared spectroscopy measurements were carried out. The appearance of a strong absorption peak confirms that PEG brushes have been grafted on the PDA-capped RGO nanosheets. | |
