摘要：
In this manuscript the influence of supercritical carbon dioxide extraction temperature on the morphology, the porosity, and the crystalline structure of syndiotactic polystyrene aerogels is investigated. Results show that depending on the extraction temperature, beta-form, gamma-form, and beta-form high porosity aerogels characterized by a fibrillar morphology can be obtained.
