Electrical and Rheological Properties of Polycarbonate/Multi-walled Carbon Nanotube Composites |
| 초록 |
Electrical and rheological properties of the polycarbonate (PC) / multi-walled carbon nanotube (MWNT) composites were studied. The MWNT was functionalized by treating with the hydrogen peroxide (H2O2) under the sonication process. For the preparation of the PC/MWNT composites, the PC/MWNT mixture, ranged from 1.0 to 7.0 wt%, was dissolved in tetrahydrofuran (THF) under the sonication process. The –COOH and –OOH groups of the MWNT by treating with the H2O2 were confirmed by the measurement of FT-IR spectra. For measuring the electrical conductivity, the four-probe method was used to eliminate the contact resistance. From the electrical properties of the PC/MWNT composites, the electrical conductivity of the PC/MWNT (H2O2 treated) composites showed higher compared that of the PC/MWNT (untreated) composites. |
