▎ 摘　　要

NOVELTY - An aqueous solution of graphene oxide is mixed with silica sol, stirred, and ultrasonically-dispersed, to obtain mixed dispersion. Mixed dispersion is sprayed into liquid nitrogen, atomized, volatile liquid nitrogen is removed and cured product is vacuum-dried, to obtain graphene oxide/silica spherical catalyst support material. The support material is added to mixed solution of tetrahydrofuran and butyl magnesium chloride and stirred, to obtain a reaction product. The reaction product is washed and heated, to obtain ultra-high-molecular weight polyethylene catalyst support material. USE - Preparation of ultra-high-molecular weight polyethylene catalyst support material (claimed). ADVANTAGE - The method efficiently and economically provides ultra-high-molecular weight polyethylene catalyst support material by effectively reducing the polymer molecular chain entanglement. DETAILED DESCRIPTION - An aqueous solution of graphene oxide is mixed with silica sol, stirred, and ultrasonically-dispersed, to obtain mixed dispersion. The mixed dispersion is sprayed into liquid nitrogen, atomized, volatile liquid nitrogen is removed and cured product is vacuum-dried in a vacuum chamber to remove moisture, to obtain sample. The obtained sample is heated, to obtain graphene oxide/silica spherical catalyst support material. The support material is added to mixed solution of tetrahydrofuran and butyl magnesium chloride, and stirred at 50-80 degrees C for 12-48 hours, to obtain a reaction product. The reaction product is washed to remove excess butyl magnesium chloride, and then heated at 400-800 degrees C for 30-120 minutes under an argon atmosphere, to obtain ultra-high-molecular weight polyethylene catalyst support material.
