NOVELTY - A graphene metallocene compound (I), is new. USE - New graphene metallocene compound used as catalyst for polymerization or copolymerization of olefins (claimed). ADVANTAGE - The graphene metallocene catalyst has excellent mechanical property and functionality such as conductivity, antibacterial property and wear resistance. DETAILED DESCRIPTION - A graphene metallocene compound of formula (I), is new. Mt = Ti, Zr, or Hf; L = Cl or group chosen from groups of formulae (a)-(d); and R = n-Bu, t-Bu, n-Hx, or n-Oct. An INDEPENDENT CLAIM is included for preparation of the compound (I), which involves dispersing dried graphene in tetrahydrofuran solvent in Schlenk flask at -10°C, dripping excess alkyllithium solution, stirring for 24 hours, filtering the suspension, repeatedly washing with tetrahydrofuran and n-hexane to remove unreacted alkyllithium, suspending obtained graphene-alkyllithium in n-hexane, dripping metal salt solution at -30°C, stirring at -30°C for 1 hour and refluxing at 70°C for 5 hours.
