Abstract

The structure, morphology and mechanical properties of polypropylene-nanoclay composites with 1 to 15 wt.% nanoclay additives were investigated. Mixture of intercalated and exfoliated morphology was observed in nanocomposites. At higher weight percentage reinforcement (10–15 wt.%), up to 67 % improvement in tensile modulus is observed. At higher weight percentage, exclusion of clay additives at the boundary of spherulites was observed. This study illustrates that along with the thermodynamic driving force, spherulite formation also drives the ultimate morphology
