Abstract
A golf ball with a mantle layer comprising an ionomer material and a graphene material in an amount ranging from 0.1 to 5.0 weight percent of the mantle layer is disclosed herein. The golf ball may multiple layers. A preferred embodiment of a golf ball comprises a core, a mantle layer and a cover.
Claims5
A golf ball comprising:
- a core;
- a mantle layer comprising an ionomer material and a graphene material in an amount ranging from 0.1 to 5.0 weight percent of the mantle layer;
- and
- a cover layer disposed over the mantle layer.

A golf ball comprising:
- a core;
- an inner mantle layer disposed over the core, the inner mantle layer having a thickness ranging from 0.03 inch to 0.09 inch, the inner mantle layer composed of an ionomer material, the inner mantle layer material having a plaque Shore D hardness ranging from 34 to 55;
- an outer mantle layer disposed over the inner mantle layer, the outer mantle layer having a thickness ranging from 0.025 inch to 0.050 inch, the outer mantle layer comprising an ionomer material and a graphene material in an amount ranging from 0.1 to 5.0 weight percent of the outer mantle layer;
- and
- a cover layer disposed over the outer mantle layer, the cover layer has a thickness ranging from 0.025 inch to 0.040 inch.
