NOVELTY - Preparing graphene/polypropylene composite material involves dispersing graphene oxide in inert solvent to obtain suspension. The obtained suspension is added with metal organic reagent and refluxed for 1-5 hours to obtain modified graphene dispersion. The obtained modified graphene dispersion is polymerized with propylene, catalyst and co-catalyst to obtain graphene/polypropylene composite material. USE - Method for preparing graphene/polypropylene composite material (claimed). ADVANTAGE - The method enables to prepare graphene/polypropylene composite material, which has improved mechanical performance, conductivity property and has improved antistatic property. DETAILED DESCRIPTION - Preparing graphene/polypropylene composite material involves dispersing graphene oxide in inert solvent to obtain suspension. The obtained suspension is added with etal organic reagent and refluxed for 1-5 hours to obtain modified graphene dispersion. The metal organic reagent is selected from RnM, RnMX or RnOM. R=1-12C alkyl, 5-12C cycloalkyl or 6-12C aryl; M=lithium, sodium, aluminum, magnesium, zinc and titanium; and X=halogen.
