Effect of additives on the dynamic bubble growth behavior of polymer foam evaluated with in-situ visualizations and simulations

Effect of CO2-philic additive additives PDMS and co-blowing agent alcohol on dynamic bubble growth behavior of supercritical CO2 assisted polymer foaming process, was investigated by using a visual observation system combined with numeric model. The addition of PDMS in PS accelerates the bubble nucl...
