The Enhancement of Electrical Conductivity and Thermoelectric Properties of PDMS/Bismuth Telluride(Bi2Te3)/CNT Composites Using Alignment of CNT by High Magnetic Field |
| 초록 |
Bismuth telluride(Bi2Te3)/multi walled carbon nanotube(MWCNT) nanocomposites were synthesized by using high energy ball milling followed by vacuum filtration and its nanocomposite was added to flexible conductive composite of polydimethyl siloxane (PDMS)/MWCNT. The surface microstructure of composites reveals that the MWCNTs are randomly dispersed among the Bi2Te3 nanopowders without severe agglomeration and well mixed with the PDMS matrix. Within the appropriate composition range, the figure of merit(ZT) of the flexible composite showed an enhanced value compared to that of simple PDMS/MWCNT composites at near room temperature due to the reduced thermal conductivity and increased electrical conductivity with the addition of Bi2Te3/MWCNT nanocomposites and alignment of MWCNTs by high magnetic field.
