Abstract
Described herein is a polyurethane including a reaction product of an isocyanate component, a polyol component, and graphene nano platelets. The graphene nano platelets are reacted in an amount of from about 0.1 to about 20% by weight, based on a total weight of the polyurethane. The graphene nano platelets have an average lateral dimension (x, y) of from about 1 to about 100 μm, an average through-plane dimension (z) of from about 5 to about 100 nm, and an oxygen content of from about 0.01 to about 10% by weight, based on a total weight of the graphene nano platelets.
