Abstract

In this study, a methodology is developed for the quantitative characterisation of the nanofiller network in polymer nanocomposites via dynamic rheometry. Nanoclay-reinforced poly(ε-caprolactone) (PCL) nanocomposites were prepared by melt mixing. Frequency sweep experiments in the melt state display at low frequencies a solid-like elastic response that can be attributed to the formation of a physical nanofiller network. Combining a semi empirical model and the time–temperature superposition principle permits a reliable determination of the zero shear modulus that characterises the solid-like response of nanocomposites at low frequency, and which is related to the nanofiller dispersion.
