Ball milling is widely used in metallurgy and mineral processing industry [96]. The principle of ball milling is to grind and mix powders in a closed space by using the huge shear force and compression force produced by hard ball collision. In the synthesis of PNCs, this method can disperse CNTs [97], graphene nanoparticles [98–101], silica nanoparticles [102], and BNs [103, 104] into thermoplastic and thermosetting polymers. The high shear force produced by ball milling can peel off some two-dimensional nanostructures, such as graphene, MoS₂, and BNs, but may not separate the interlayer structure connected by ionic bonding [105–110]. In addition, ball milling is not only suitable for solvent-free conditions but also solvent-free conditions, so nanofillers can be directly dispersed in some solid thermoplastic matrix, such as polyethylene (PE) [101, 111], polyphenylene sulfide [104, 112], and polymethyl methacrylate (PMMA) [102].
