Desarrollo de métodos sintéticos basados en química click para la preparación de materiales avanzados grafeno-polímero

The field of polymer nanocomposites (PNCs) has evolved significantly in the last years, mainly as a consequence of the isolation of individual layer in graphene, one of the best candidates as filler so far. PNCs represent an alternative to conventional composite materials since they achieve specific...
