Abstract
An improved rubber composition and method to create the improved rubber composition is achieved by milling reduced graphene oxide (“RGO”) in liquid rubber to induce a reduction of bulk density of the reduced graphene oxide while maintaining dispersibility in rubber without using a solvent-based process resulting in an industrially scalable process and an improved rubber composition.

A method of manufacturing a reduced graphene oxide reinforced rubber composition, the method comprising:
- milling the reduced graphene oxide with a liquid rubber to form a milled material;
- mixing an uncured rubber elastomer;
- adding the milled material to the uncured rubber elastomer and mixing;
- adding an anti-degradant package and mixing;
- adding a curing package
- milling the rubber mixture until full incorporation of the curing package.
