Abstract

The development of synthetic composites with controlled composition, morphology and local texture is little explored due to the lack of processing routes. Two dimensional (2D) MoS2 is a great candidate to be part of complex materials and it is the lamellar transition metal dichalcogenide most studied in the world, owing to its superior mechanical properties. Recently, 2D-MoS2/polymer composites have been developed to obtain polymer nanocomposites with improved mechanical properties. Composites presenting inorganic particles interconnected by polymer chains are stronger and stiffer than those composites without this kind of bond. We propose the assembly of MoS2 applying an external magnetic field and a controlled radical polymerization of the oriented material to obtain a continuous reinforcement network dispersed in a polymer matrix that could be processed using techniques commonly applied to process discontinuous composites. These composites will be characterized in order to study their structure and morphology and their mechanical behavior will be investigated by quasi-static and fracture mechanics tests.
