▎ 摘 要
NOVELTY - A method of manufacturing polyester chips of graphene, including the following steps: melt-mixing a polymer material and a graphene powder having a mass fraction 2 wt%, and sequentially melt-mixing a tackifier with a mass fraction between 1 wt% and 3 wt%, a toughener with a mass fraction between 1 wt% and 3 wt%, and a dispersant with a mass fraction between 1 wt% and 4 wt%. Finally, a molten material is made into a plurality of polyester chips of graphene each in a shape of short cylindrical particles. The disclosure further includes a method of manufacturing a diaphragm of graphene.
