Abstract: In order to study the effect of Al2O3@SiO2 core-shell nanoparticles on the properties of polypropylene (PP) nanocomposites, spherical Al2O3@SiO2 core-shell nanoparticles were synthesized by the surface precipitation method, and the PP nanocomposites with Al2O3@SiO2 core-shell nanospheres were prepared. The physicochemical properties, dielectric spectra, and space charge properties of PP nanocomposites with different contents of Al2O3@SiO2 nanoparticles were studied. The experimental results show that Al2O3@SiO2 nanospheres reduce the sto-rage modulus of PP nanocomposites and enhance their toughness. The filler content of Al2O3@SiO2 nanospheres has an evident effect on the dielectric properties and space charge properties. When the filler content is low, the core-shell structure of Al2O3@SiO2 nanospheres enhances the compatibility between fillers and the matrix and the interaction in the interface region, which further affects the charge density and carrier mobi-lity. Consequently, the relative permittivity and dielectric loss factor of PP nanocomposites decrease. The heterocharge accumulation is also suppressed, improving PP nanocomposites' dielectric and space charge properties.
