Abstract
The present invention provides a sole for a footwear article. The sole is formed from an elastomeric compound comprising at least one elastomer, and at least one graphene based material, in an amount ranging from 0.1 wt % to 5 wt % relative to the weight of said at least one elastomer, essentially uniformly distributed in said at least one elastomer.
Claims5
A sole for a footwear article, said sole is formed from an elastomeric compound comprising:
- a natural rubber or a rubber compound containing natural rubber, and
- at least one graphene-based material, in an amount ranging from 0.1 wt % to 1 wt % relative to the weight of said natural rubber or said rubber compound containing said natural rubber, essentially uniformly distributed in said natural rubber or said rubber compound containing said natural rubber, wherein said graphene based material comprises any one or any combination of single-layer graphene sheets and/or multi-layer graphene sheets and/or single-layer graphene oxide sheets and/or multi-layer graphene oxide sheets, and wherein said single-layer graphene sheets, said multi-layer graphene sheets, said single-layer graphene oxide sheets and said multi-layer graphene oxide sheets have a mean lateral particle size of 1 μm with a standard deviation in the region of 2 μm.
