Journal of Engineering Thermophysics Aims and scope

Abstract

It is shown that theoretical models elaborated for polymer microcomposites are not capable to describe variation of the melt viscosity of polypropylene/globular carbon nanocomposites at change in the nanofiller contents. Then a fractal model of viscosity is proposed, which takes into account the sizes of nanofiller aggregates and their surface structure. This model shows a good agreement with experimental data. It demonstrates a fundamental difference in the behavior of melt viscosity for polymer micro- and nanocomposites.
