▎ 摘　　要

NOVELTY - Manufacturing graphene ester particle comprises melting and mixing the high molecular material and graphene powder with less than or equal to2 wt.%, preparing into each short cylindrical granular graphene master batch, melting and mixing the graphene master batch with 1-3 wt.% tackifier, 1-3 wt.% toughening agent and 1-4 wt.% dispersant, melting and mixing with the graphene master batch, the tackifier, the toughening agent and the melting raw material of the dispersant are made into graphene ester particles of short cylindrical particles. USE - The method is useful for manufacturing graphene ester particles. ADVANTAGE - The method solves the technical problems of high difficulty in the process of film, complicated process steps, uneven quality of the mold, and difficulty in reducing the manufacturing cost and is easy to manufacture at low-cost. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for manufacturing graphene diaphragm, comprises melting the graphene ester particle and biaxially stretching the molten graphene ester particles by a biaxial stretching machine to form a graphene vibration film, where the polymer material includes polyethylene terephthalate
