Embodiment 1
[0019] Take 2 mL of a 100 mg / mL graphene oxide solution dissolved in DMF and a powder particle size of 40 μm in a 25 mL flask, add 12 mL of deionized water and 300 μL of triethylamine to it, and add 20 mg of thiol during 20 minutes of nitrogen gas flow. Sodium acetate, stirred and reacted at room temperature for 2 days to obtain thioester-modified latent sulfur graphene oxide. The obtained product was washed with deionized water and stirred for 24 hours to obtain mercapto-modified graphene oxide. The obtained mercapto-modified graphene oxide product was characterized by XPS spectrum, infrared spectrum and Raman spectrum. The XPS spectrum of the mercapto-modified graphene oxide ( figure 2 ) and the XPS spectrum of graphene oxide ( figure 1 ) for comparison, it can be found that 1.06% of sulfur elements appeared in the mercapto-modified graphene oxide product, indicating that the introduction of mercapto groups may be successful; the infrared spectrum of the mercapto-modified...
Embodiment 2
[0021] Take 2 mL of 100 mg / mL graphene oxide solution dissolved in DMF in a 25 mL flask, add 12 mL of deionized water and 300 μL of triethylamine to it, add 60 μL of thioacetic acid during 20 minutes of nitrogen gas flow, and put The reaction was stirred for 2 days to obtain thioester-modified latent sulfur graphene oxide. The obtained product was washed with deionized water and stirred for 24 hours to obtain mercapto-modified graphene oxide.
Embodiment 3
[0023] Take 2 mL of 100 mg / mL graphene oxide solution dissolved in DMSO in a 25 mL flask, add 12 mL of deionized water and 300 μL of triethylamine to it, add 60 μL of thioacetic acid during 20 minutes of blowing nitrogen gas, and incubate at 40 °C The reaction was stirred for 2 days to obtain thioester-modified latent sulfur graphene oxide. Add 100 mL of 5% dilute hydrochloric acid to the obtained product, then wash with deionized water, and stir for 24 hours to obtain mercapto-modified graphene oxide.
