摘要

Polymer foams prepared with supercritical carbon dioxide as a blowing agent have attracted much interest in recent years. Yet, a thorough understanding of the foaming process, especially nucleation, is absent. In this article, the influence of one characteristic property of polymer, molecular weight, on the nucleation rate and cell growth rate is investigated by an in-situ observation introduced by high speed camera. Moreover, the influence of these two properties on the solubility of carbon dioxide in the polymer is investigated by using a magnetic suspension balance while simultaneously measuring the swelling coefficient during adsorption.
