Enhanced Thermoelectric Properties in PDMS/MWCNT Based Flexible Composites Using Modification of MWCNT with Magnetic Iron Oxide and Its Alignment by High Magnetic Field |
| 초록 |
Magnetic Fe3O4 nanoparticle attached onto surface of MWCNTs(m-MWCNTs) were synthesized and their electrical conductivities as a result of their alignment in a flexible composite(PDMS/MWCNT) matrix under an external high magnetic field were investigated. Especially, m-MWCNTs were readily aligned parallel to the direction of a magnetic field(MF) compare to pristine MWCNT. The electrical conductivity of the flexible composites was increased with increasing m-MWCNTs content in the PDMS/MWCNT composite matrix. Futhermore, the electrical conductivity parallel to the direction of MF were higher than those in the random. Also, Bi2Te3 particles added to the PDMS/MWCNT mixture and fabricated composite sample under same condition. The thermoelectric parameters such as thermal conductivity, Seebeck coefficient, and the calculated ZT have been investigated.
