Abstract

Using the Polypropylene (PP) as the continuous phase matrix and the Alumina (Al2O3) as functional filler, the Al2O3-filled PP matrix composites were fabricated after the surface modification of Al2O3 by silane coupling agent KH-570. The effects of Al2O3 with different particle sizes and different filling amounts on the mechanical properties, thermal stability, dielectric properties and melting crystallization behavior of the composites were studied. The research results show that as the particle size of Al2O3 increases, the impact strength of composites gradually rises. With the increase of Al2O3 filling amount, the tensile modulus and bending modulus of the composite material gradually increase, as well as the thermal decomposition temperature. In addition, the crystallization temperature and the dielectric constant of the composite material enhance as the increase of Al2O3 filling amount, but the melting temperature does not change much.
