“…It also improves the thermal stability, mechanical, gas barrier, electrical conductivity and molding properties of such blends [ 4 , 5 , 6 , 7 , 8 , 9 ]. Immiscible polymer blends with metal NPs (e.g., polyethylene/polybutylene terephthalate/silver [ 10 ], polyethylene/polyethylene oxide/silica [ 11 ]), metal oxide (e.g., SiO 2 , ZnO and TiO 2 ) NPs and carbon nanomaterials (e.g., carbon nanotubes)) are widely used in various industries, including automotive, packaging and food industries [ 12 , 13 , 14 ]. Currently, the main challenge is to optimize the polymer blend composition to minimize NP aggregation and polymer phase separation [ 15 , 16 ].…”
