1. A method for forming a golf ball with a graphene core, the method comprising:
mixing a graphene masterbatch material with a polybutadiene material, zinc diacrylate, zinc oxide, and a peroxide initiator to form a core mixture, wherein the graphene masterbatch material comprises graphene in an amount from 0.1 to 80.0 weight percent of the graphene masterbatch material mixed with a carrier polymer in an amount from 99.9 to 20 weight percent of the graphene masterbatch material; and
compression molding a core from the core mixture, wherein the core mixture comprises 40-90 weight percent of polybutadiene, 0.4 to 2.5 weight percent graphene material, 1-30 weight percent polyisoprene, 10-50 weight percent zinc diacrylate, 1-30 weight percent zinc oxide, 1-20 weight percent zinc stearate, and 0.1-10 weight percent peroxide initiator;
injection molding a mantle layer over the core; and
forming a cover over the mantle layer.
