Abstract
The crystal morphologies of poly(ε-caprolactone) solvent-cast films in the absence and presence of multi-walled carbon nanotubes were observed using polarized optical microscopy. The experimental results indicated ring-banded spherulites containing polygonal holes could be induced by dewetting on the surface of the substrate. The polymer crystals assembled into a hierarchical structure induced by the change of the crystallization temperature. Further it was found that the loading of nanotubes into polymer matrix could change the ring-banded structure in the spherulites.
期刊介绍：
Polymer Science, Series A is a journal published in collaboration with the Russian Academy of Sciences. Series A includes experimental and theoretical papers and reviews devoted to physicochemical studies of the structure and properties of polymers (6 issues a year). All journal series present original papers and reviews covering all fundamental aspects of macromolecular science. Contributions should be of marked novelty and interest for a broad readership. Articles may be written in English or Russian regardless of country and nationality of authors. All manuscripts are peer reviewed. Online submission via Internet to the Series A, B, and C is available at http://polymsci.ru.
