Preparation of microcellular polystyrene/polyethylene alloy foams by supercritical CO2 foaming and analysis by X-ray microtomography

- PS/PE alloy foam was prepared by supercritical carbon dioxide foaming method.
- The addition of SEBS copolymer remarkably improved the cell morphology of the PS/PE alloy foams.
- A non-destructive X-ray microtomography (XMT) was employed to observe the cell morphology of the PS/PE alloy foams.
