| 제목 | Properties of Polycarbonate/Multi-walled Carbon Nanotube Composites |
| 초록 | Morphological, electrical and electromagnetic interference shielding efficiency (EMI SE) 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 effects of the MWNT functionalization by H2O2 was observed by SEM and TEM image. For measuring the electrical conductivity, the four-probe method was used to eliminate the contact resistance. For measuring EMI SE, it was used vector network analyzer (VNA) with the 2-ports flanged coaxial line holder. From the electrical and EMI SE properties of the PC/MWNT composites, the electrical conductivity and EMI SE of the PC/MWNT (H2O2 treated) composites showed higher compared that of the PC/MWNT (untreated) composites.
