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 &#x3bc;m, 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.

Polyurethane comprising graphene nano structure

Described herein is a cast elastomer including graphene nano platelets and a process for preparing the same.

A hybrid composition includes an isocyanate, a polyester having at least one carbon-carbon double bond and at least one hydroxyl group, castor oil present in an amount of from 5 to 30 weight percent, a catalyst, and a solvent. The hybrid composition can be formed using various methods. The method may include combining the isocyanate and the castor oil to form a first adduct, combining the polyester, the solvent, and the catalyst to form a second adduct, and combining the first adduct and the second adduct. The method may alternatively include combining the castor oil, the solvent, and the polyester to form a third adduct, combining the third adduct with the isocyanate, and combining the catalyst with the third adduct and the isocyanate. The method may alternatively include combining the catalyst and the isocyanate component to form a fourth adduct, and combining the third and fourth adducts.
