In this work, we will basically describe, the studies that we are conducting in our research group, of how an adequate and directional functionalization can control the mechanical properties of elastomeric and thermosets nanocomposites. We will describe the mechanical properties of elastomers based on modified polybutadiene with MoS2 and how the soft organic layer of nanoparticle (Fe3O4) modify the mechanical properties of elastomers based on PU and epoxy matrices. A special emphasis will be given in the preparation of the colloidal suspensions.
