摘要: Multi-walled carbon nanotubes (MWNTs) were sonicated in the dimethylformamide solution of poly(vinylidene fluoride) (PVDF). The PVDF-covered MWNTs then melt-blended with poly(methyl methacrylate) (PMMA). dynamic mechanical behavior various composites was studied. presence a small amount PVDF leads to significant improvement storage moduli MWNT/PMMA at low temperatures. modulus PVDF/MWNT/PMMA composite containing 0.5 wt.% is almost twice as that 50°C. However, further increase content reduction modulus. beneficial effect diminishes higher
