As a new approach, the location of nano-filler was monitored in the polypropylene/ethylene propylene diene monomer (PP/EPDM) blend using atomic force microscopy (AFM), dynamic mechanical thermal analysis (DMTA) and surface parameters and then the effect of nanoclay distribution on the final foam morphology was discussed. The results revealed that the organoclays have more affinity with PP and foaming is mainly occurred in PP phase. It seems the location of nanoparticles in this phase facilitated the nucleation via heterogeneous nucleation mechanism.
