The use of supercritical CO2 (scCO2) in polymer processing has been paid significant attentions in polymer science over the past decade. The physical properties of the scCO2 can be tuned by slight adjustments to either the pressure or temperature conditions, allowing for tailored solvent properties. All of the scCO2 processes are based on the ability of the scCO2 to swell and plasticize a polymer. In this study, we investigated the use of scCO2 as a blowing agent for fabrication of microcellular foam of nylon 12 elastomers using a batch process. Effects of foaming conditions such as pressure, temperature, and swelling time on the morphology of the foam were examined. |
