Graphene core for a golf ball
View Patent ↗A golf ball with a core comprising polybutadiene and graphene is disclosed herein. The golf ball has a single core comprising polybutadiene and graphene. Alternatively, the golf ball has a dual core with an inner core comprising polybutadiene and graphene. Alternatively, the golf ball has a dual core with an outer core comprising polybutadiene and graphene.
1. A method for forming a core for a golf ball, the method comprising:
mixing a graphene material with a polybutadiene material to form a core mixture, wherein the core mixture comprises 40-90 weight percent of polybutadiene, 0.4 to 2.5 weight percent graphene material, 10-50 weight percent zinc diacrylate, 1-30 weight percent zinc oxide, and 0.1-10 weight percent peroxide initiator, wherein the graphene material has a surface area ranging from 150 m 2 /g to 1000 m 2 /g; and
compression molding an outer core from the core mixture around an inner core to form a dual core.
2. The method according to claim 1 wherein the dual core has a diameter ranging from 0.70 inch to 1.6 inch.
