Abstract
The present invention provides relates to a polypropylene-graphene composite and a method for preparing the same, and in particular, relates to a polypropylene-graphene composite more uniformly dispersing graphene oxide into a polypropylene polymer substrate without graphene oxide aggregation and thereby obtaining an effect of enhancing mechanical properties of the composite even when a small amount of graphene oxide is added, by, in preparing the composite from mixing graphene oxide to a polypropylene polymer substrate, activing a surface of the graphene oxide with aminoalkyl trialkoxysilane, then preparing graphene oxide master batch powder organophilized through an amide bond with maleic anhydride-grafted polypropylene and mixing the graphene oxide master batch powder, and a method for preparing the same.
