Abstract: In the polymer foam industry, emphasis is placed on improving foam properties and making the production process more sustainable and ecological. By reducing the cell size of polymer foams below tens of micrometres we can improve their heat insulation properties and save material. Such polymer foams are called micro- or nanocellular foams depending on the range of their cell size. Micro- and nanocellular foams can be prepared by pressure induced foaming with high pressure CO2. We studied the influence of the foaming conditions on the final foam structure with the aim of achieving the cell sizes as small as possible, having a narrow cell size distribution and reaching the bulk porosity above 90 %. The foam morphology was analysed by Scanning Electron Microscopy and Atomic Force Microscopy. Some morphology visualisations were also made by X-ray micro-tomography, but these visualisations are not demonstrated in this contribution.
Keywords: impregnation temperature; micro- and nanocellular foams; X-ray micro-tomography
