NOVELTY - Graphite oxide and alkylamine with thiol are added to reaction solvent, in mass ratio of 1:0.01-10, stirred, and reacted at 0-90 degrees C for 0.1-72 hours, to obtain thiol-modified graphite oxide. The thiol-modified graphite oxide and reducing agent are added to reaction solvent, stirred, reacted at 0-90 degrees C for 0.1-72 hours, filtered, washed and dried, to obtain mercapto modified graphite oxide. USE - Preparation of mercapto modified graphene oxide used for electrochemical electrode, optical and conductive material.
