Spherulite nucleation density from thin sections of bulk samples
Abstract
The determination of bulk spherulite nucleation density from micrographs of thin random sections is discussed. The influence of the time dependence of nucleation on average number of spherulites in a volume unit of a polymer, determined from thin sections, is estimated based on the computer simulation of spherulitic crystallization. The relevance of the proposed method is verified experimentally. The average number of spherulites in commercial isotactic polypropylenes and in nanocomposites of isotactic polypropylene with montmorillonite with bimodal nucleation are calculated. The results allow to estimate better the nucleation effect of montmorillonite on crystallization of nanocomposites
