The mixing of the filler and the polymer matrix implies different processes e.g., (i) incorporation, (ii) distribution and (iii) dispersion of the filler. The dispersion process corresponds to the reduction of the size of the filler introduced as agglomerated pellets (a few hundred microns) down to the size required for the aimed properties during the mixing operation. For mechanical properties, the objective is to decrease the size to the smallest achievable size (nanometric size for nanofillers). Dispersion and distribution processes will define the dispersion state of the filler in the final product and thus its end-use properties.
