To assist design and development of SMARTFAN materials with specific multi-functionalities Multi-physics modelling tools have been applied. In particular, multiscale simulation has been performed to understand the influence of graphene-reinforcement on the thermo-physical properties on polymer nanocomposites. The study shows that the mechanical strength of composite is improved by more than 30% compared to neat polymer by addition of 2 wt% of graphene, while the effect of graphene reinforcement on thermal properties is negligible.
