A composition and method for fabricating graphitic nanocomposites in solid state matrices is presented. The process for fabricating graphitic nanocomposites in solid state matrices may include selecting one or a mixture of specific graphitic nanomaterials. The graphitic nanomaterial(s) may be functionalizing with a moiety similar to the building blocks of the solid state matrices.
