초록

We prepared polycarbonate (PC)/poly(methyl methacrylate) (PMMA)/multiwall carbon nanotube (MWCNT) nanocomposites
by co-rotating twin screw extruder at 533 K. Thermal analysis results indicate that the miscibility of PC and
PMMA is enhanced by MWCNTs. Bead necklace-like morphology of PMMA-rich phase is observed in PC/PMMA/
MWCNT nanocomposites with increasing PMMA weight fraction due to the bead necklace-like morphology. The tensile
strength of PC/PMMA (75/25)/MWCNT (1 wt.%) nanocomposite is 3% higher than those of PC/PMMA (75/25) alloy.
Suppression of die swell by MWCNT filler is observed in the melt flow of PC/PMMA/MWCNT nanocomposites during
extrusion.
