摘要

Abstract

Various phase structures can be formed by rubber and rigid particles in a polymer. Which is more beneficial to the impact toughness and rigidity

as well as their balance. This has been unclear until now. In this study

polymer composites with typical three-phase structures

that is

hard core-soft shell particles

soft core-hard shell particles

and two types of separated particles

were studied theoretically. The calculated results indicate that the soft core-hard shell structure is the best

for enhancing the modulus in these three-phase structures

whereas the hard core-soft shell structure is the worst. On the other hand

both core-shell structures are beneficial for enhancing toughness

whereas the two types of particle-separated structures are not. These theoretical results are supported by the experimental results for polypropylene (PP)

ethylene-propylene-diene monomer (EPDM) rubber

and SiO

composites.
