Abstract

Interfacial interactions significantly influence the properties of heterogenous polymer systems, including particulate-filled thermoplastics. The size of the interface and the strength of the interaction determine the adhesion between the phases and the amount of interphase formed. In our experiments, PP composites were prepared with diverse CaCO3 fillers. The size of the interphase was changed by changing the specific surface area of the filler, while the strength of the interaction was influenced by stearic acid surface treatment. Tensile properties of the composites were determined and the effect of interfacial interaction was evaluated by semi-empirical equations developed earlier. The results have shown that changing interaction exerts widely differing influence on the different properties; modulus is hardly influenced by it, while the dependence of yield and failure properties is strong. These differences can be explained by the adhesion of the polymer chains to the filler surface. Interaction influences also the failure mode, weak interaction results in extensive dewetting and stable crack propagation, while in the case of strong interaction, brittle fracture prevails.
