Methods of forming graphene functionalized carbon nanotube polymer composites are provided. The methods can include functionalizing a plurality of carbon nanotubes using conducting functional molecules to form a composite nanofiller and embedding the composite nanofiller within a polymer material to form the graphene functionalized carbon nanotube polymer composite.

Graphene functionalized carbon nanotube polymer composites and methods for their preparation and use

Technologies are generally described for forming a nanofluid coolant and structures including a nanofluid coolant. In an example, a method of forming a nanofluid coolant may comprise combining a compound with an acid and with purified water to form a solution. The compound may include manganese. The method may further include heating the solution and, after heating the solution, cooling the solution effective to form at least one precipitate that includes manganese and oxygen. The method may further include filtering the at least one precipitate to form a powder that includes manganese oxide nanotubes. The method may further include functionalizing the nanotubes by irradiating them with UV radiation. The method may further include combining the functionalized manganese oxide nanotubes with a polar solvent to form the nanofluid coolant.
