NOVELTY - A graphene gel comprises graphene and nonionic surfactant in weight ratio of 1:100. The non-ionic surfactant is polyethylene glycol. USE - Graphene gel (claimed). DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of graphene gel, which involves preparing graphene from graphite by oxidation-reduction method, oxidizing graphite through improved hummers method, adding zinc powder in the acid with metal, performing rapid reduction under ultrasonic condition, adding nonionic surfactant, mechanically grinding for 20 minutes, uniformly dispersing graphene in surfactant, removing supernatant, centrifuging, resulting excess nonionic surfactant, and obtaining lower graphene oxide/polyethylene glycol gel.
