  • Polypropylene/silica micro- and nanocomposites modified with poly(styrene-b-ethylene-co-butylene-b-styrene)
    Pustak, Anđela ...
    The effects of different silica loadings and elastomeric content on interfacial properties, morphology and mechanical properties of polypropylene/silica 96/4 composites modified with 5, 10, 15, and ... 20 vol % of poly(styrene-b-ethylene-co-butylene-b-styrene) SEBS added to total composite volume were investigated. Four silica fillers differing in size (nano- vs. micro-) and in surface properties (untreated vs. treated) were chosen as fillers. Elastomer SEBS was added as impact modifier and compatibilizer at the same time. The morphology of ternary polymer composites revealed by light and scanning electron microscopies was compared with morphology predicted models based on interfacial properties. The results indicated that general morphology of composite systems was determined primarily by interfacial properties, whereas the spherulitic morphology of polypropylene matrix was a result of two competitive effects: nucleation effect of filler and solidification effect of elastomer. Tensile and impact strength properties were mainly influenced by combined competetive effects of stiff filler and tough SEBS elastomer. Spherulitic morphology of polypropylene matrix might affect some mechanical properties additionally.
