Description
Summary:O644.2%TQ316; The 60Co γ radiation effect on spherical open-porous polymethylphenylvinyl siloxane foam was studied in different atmospheres at room temperature. The physical and chemical behaviors of unirradiated and irradiated materials were studied by SEM, FTIR, TG (thermal gravity analysis), GC/MS(gas chromatography and mass spec troscopy), etc. The present results indicate that the yields of gas products increase linearly with the dose increasing. Furthermore, some changes in material's microscopic form, composition, structure and mechanical property were observed, but the maxi mum thermal decomposition temperature of the sample alters little and the dose gives no effect on it.
