Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
We claim as our invention the following: 1. A golf ball comprising: a core comprising polybutadiene in an amount ranging from 40 to 90 weight percent of the core, zinc diacrylate in an amount ranging from 10 to 50 weight percent of the core, zinc oxide in an amount ranging from 1 to 30 weight percent of the core, zinc stearate in an amount ranging from 1 to 20 weight percent of the core, peroxide initiator in an amount ranging from 0.1 to 10 weight percent of the core, and a graphene material in an amount ranging from 0.1 to 5.0 weight percent of the core; and a cover layer disposed over the core. 2. The golf ball according to claim 1 wherein the graphene material ranges from 0.4 to 2.5 weight percent of the outer core. 3. The golf ball according to claim 1 wherein the graphene material ranges from 0.6 to 1.5 weight percent of the outer core. 4. The golf ball according to claim 1 wherein the graphene material has a surface area ranging from 400 m 2 /g to 800 m 2 /g. 5. The golf ball according to claim 1 wherein the graphene material has a surface area ranging from 15 m 2 /g to 50 m 2 /g. 6. The golf ball according to claim 1 wherein the graphene material has a surface area ranging from 300 m 2 /g to 400 m 2 /g.
