摘要: A method for preparing a carbon powder from an organic polymer material and a method for detecting the crystal morphology in the organic polymer material. A method for preparing a carbon material product comprises a carbonization step in which: a straight-chain polymer material containing nanoscale crystals is carbonized by using a strong oxidizing agent free of heavy metal ions, thus acquiring a nanoscale carbon material. Also disclosed is a method for acquiring either a material having a carbonized surface or a powder material containing graphene by using an acid in treating the organic polymer material.

摘要: The present invention relates to a method for preparing a sulfonated graphene from an organic material and to the sulfonated graphene prepared therefrom. The method comprises the following steps: a first contact step: a reaction medium containing oxidative sulfonating agent is allowed to come into contact with the organic macromolecular material at a first temperature; and, a second contact step: when the first contact step is completed, in same reaction medium, the reaction temperature is increased to a second temperature to allow for continued reaction, thus producing the sulfonated graphene.
