Problems solved by technology

[0004] With the development of nanotechnology, the compounding of graphene nanomaterials and substrates to make conductive polymer materials is becoming more and more popular; The addition of the polymer material can greatly improve the conductivity of the polymer material and reduce its conductive percolation value, but at present, the graphene is directly filled into the coating, and the graphene is difficult to disperse evenly in the coating, which will lead to a decrease in the related performance of the coating. , so modifying graphene so that it can be dispersed evenly in the coating has important application value for improving the performance of antistatic coatings and conductive polymer composites
