1. A method of forming a nanocomposite fiber, comprising:

suspending carbon powder comprising pristine graphene flakes in a carrier fluid;

adding a solid polymer material to the carrier fluid having the carbon powder suspended therein to create a mixture;

heating the mixture and at least partially dissolving the solid polymer material within the carrier fluid having the carbon powder suspended therein; and

removing the carrier fluid from the mixture and forming a polymer into a fiber carrying the graphene flakes.
