|초록||Electircal, rheological, and dynamic mechanical properties of the PC/ MWNT composites were studied. PC/MWNT composites were prepared by dilution of a masterbatch using the melt extrusion. From the results of electrical conductivity and rheological measurements, the electrical and rheological percolation threshold of the composites showed at 1.5 wt% MWNT content. For the PC/MWNT composites containing the low content of the MWNT (≤ 4.0 wt%), single tan δ peak which corresponded to the Tg of the PC was observed. For the PC/MWNT composites containing the high content of the MWNT (≥ 7.0 wt%), double tan δ peaks were observed, which could be explained by the phase separation morphology model.
