Study on Dynamic Mechanical Behavior of PA6/SiO_2 Nanocomposites

PA6/SiO_(2) nanocomposites were synthesized by three different methods in the same polymerization conditions. The dynamic mechanical behaviors of these three composites and pure PA6 were investigated by dynamic mechanical analyzer Reometric Scientific~(TM) DMTA.The results showed that the γ,β relaxation peak temperatures of these composites moved to higher temperature than the respective temperature of the pure PA6.The dynamic storage moduls of nanocomposites synthesized by our modified method were obviously higher than that of pure polyamide 6 and nanocomposites made by other two methods.
