NOVELTY - The preparation of master batch for graphene/PVC composite material involves adding graphene to solvent, scattering to obtain mixed solution (I), adding solvent to PVC so that PVC is dissolved to obtain mixed solution (II), mixing mixture of mixed solution (I) and mixed solution (II) and drying. USE - Preparation of master batch for graphene/PVC composite material (claimed). ADVANTAGE - The method enables preparation of master batch for graphene/PVC composite material with high performance and wide application range. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for masterbatch comprises 40-90 pts. wt. PVC, 0.1-25 pts. wt. graphene, 0.1-15 pts. wt. carbon nanotubes, 0.1-15 pts. wt. carbon fiber and 0.1-25 pts. wt. carbon black.
