Ball milling has also been shown to modify the filler morphology [54], which enhances the compatibility of fillers with polymer blends [55], [56], [57], and enables successful grafting reactions [49], [58]. In addition, ball milling has been used to mix filler nanoparticles and the polymer matrix in the solid state prior to melt compounding [59].
