▎ 摘　　要

NOVELTY - The method for producing graphene, involves: providing a polymeric graphene precursor comprising donor atoms, subjecting the polymeric graphene precursor to a bulk thermal heat treatment at 600-1600, preferably 800-1200degreesC in the presence of an inert gas to produce graphene and subjecting the graphene obtained from the bulk thermal heat treatment to mechanical exfoliation treatments, where the exfoliation treatments comprises ball milling. USE - Method for producing graphene used in a filter, rubber, carbon fibre composite, or metal or metal alloys (claimed). ADVANTAGE - The method produces graphene at low cost and high production rates. The method enables graphene to be obtained at ambient pressure, with minimal chemical waste and without using harsh chemical conditions, thus can be produced in a safe and environmentally friendly manner. t has been found that the doped graphene exhibits a high degree of hydrophilicity and as a consequence, relative to pristine graphene, the doped graphene exhibits improved wettability and dispersibility in solution which avoids agglomeration. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the graphene. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a diagram showing the method for producing doped graphene
