We investigate new materials composed of Quantum dots and graphene using self-assembled systems obtained with surfactant and polymers previously characterized by the group. The main objective is to obtain a rational basis for the use of these nanomaterials in their numerous technological applications. Therefore, we study the effect of the self-assembled materials on the structure and properties of these new nanomaterials.
