Polymer Supercritical CO2 Foaming under Peculiar Conditions: Laser and Ultrasound Implementation
The two-step batch foaming process of solid-state assisted by supercritical CO2 is a versatile technique for the foaming of polymers. In this work, it was assisted by an out-of-autoclave technology: either using lasers or ultrasound (US). Laser-aided foaming was only tested in the preliminary experiments; most of the work involved US. Foaming was carried out on bulk thick samples (PMMA). The effect of ultrasound on the cellular morphology was a function of the foaming temperature. Thanks to US, cell size was slightly decreased, cell density was increased, and interestingly, thermal conductivity was shown to decrease. The effect on the porosity was more remarkable at high temperatures. Both techniques provided micro porosity. This first investigation of these two potential methods for the assistance of supercritical CO2 batch foaming opens the door to new investigations. The different properties of the ultrasound method and its effects will be studied in an upcoming publication.
