Morphological Changes of Irradiated PMMA via Supercritical Carbon Dioxide Treatments

Article Preview

Abstract:

Poly (methyl methacrylate) (PMMA) sheets were radiated by 60Co γ-ray in air and then irradiated PMMA foams were successfully prepared by supercritical CO2 (SC CO2) as a physical blowing agent via pressure quench method. The effects of radiation dose on the cell morphology and structure of the obtained foams were studied. The results showed that the foams possessed spherically closed cell structure with uniform cell size. The γ-ray irradiated PMMA sheets had a high cell density than those virgin PMMA.
