Preparation of microcellular low-density PMMA nanocomposite foams: Influence of different fillers on the mechanical, rheological and cell morphological properties

Physisorption measurements showed that TRGO and CB fillers were more CO2-phillic in comparison to talc and may have contributed to increasing the amount of CO2 retention as confirmed by sorption measurements. These features were exploited to prepare closed-cell microcellular low-density PMMA nanocomposite foams via batch-foam process.
