Description
Summary:The present paper is dedicated to fabrication of microcellular PP-MMT nanocomposite foams blown by CO2 at 3-7 MPa pressure range. XPD and TEM studies showed that MMT particles were well exfoliated upon PP-MMT nanocomposite processing, however presence of the nanoclay particles did not facilitate the foaming process, resulting in non-uniform cell structure and low expansion ratios. SEM images demonstrate that clay nanoparticles have not improved the foam morphology; and no nucleation effect of the clay was observed in the produced foams. These data were supported by DSC studies. [PUBLICATION ABSTRACT]
