NOVELTY - Manufacture of hematoxylin-modified graphene oxide involves adding alkaline solution to a graphene oxide dispersion liquid, uniformly mixing, adding hematoxylin, reacting the mixture at 20-100 degrees C, centrifuging and washing. USE - Manufacture of hematoxylin-modified graphene oxide used for forming graphene film for supercapacitor. ADVANTAGE - The method is environmentally-friendly, and enables simple, efficient and economical manufacture of hematoxylin-modified graphene oxide with excellent dispersion stability (due to addition of hematoxylin as a reducing agent and without adding stabilizers), and water solubility.
