NOVELTY - Preparing amphiphilic graphene oxide nanomaterial comprises (1) loading graphene oxide on substrate to obtain substrate carrying graphene oxide, and (2) placing substrate carrying graphene oxide in solution containing modifier, obtaining substrate carrying modified graphene oxide, and removing substrate to obtain amphiphilic graphene oxide nanomaterial. USE - The amphiphilic graphene oxide nanomaterial is useful in oil displacing agent, environmentally friendly surfactant, and oil stain treatment (claimed). ADVANTAGE - The method: realizes high yield; and is environmentally friendly. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for amphiphilic graphene oxide nanomaterial.
