Microcellular Foaming of (Nano)Biocomposites by Continuous Extrusion Assisted by Supercritical CO2

Abstract : In many industrial fields, the development of porous and light polymer composite structures is of great interest. Continuous extrusion assisted by supercritical carbon dioxide (sc-CO2) is an emerging technology for the microcellular foaming of polymer and composite materials. Thanks to its specific physical properties, sc-CO2 can act as a removable plasticizer and physical blowing agent during processing. Unlike chemical foaming processes, sc-CO2 assisted extrusion avoids leaving residues in the final products. It also allows a rapid mixing and dissolution of sc-CO2 in the polymer melt as compared to batch processes. In this chapter, the foaming of biopolymer matrices by sc-CO2 assisted extrusion is reviewed and extended to the development of (nano)biocomposites foams loaded with micro/nano-sized (in)organic fillers.
