Electrical properties of polyurethane composite filled with Ag nanoparticles encapsulated into MWCNT |
| 초록 |
The electrical properties of Ag nanoparticles encapsulated into the inside of multiwalled carbon nanotube (MWCNT) and polymer composite thin film have been investigated, where the MWCNTs are oxidized with respect to various oxidative conditions. The encapsulation of Ag nanoparticles into the MWCNTs can be achieved by thermal annealing at high temperature after the reduction reaction of mixture of pre-dispersed MWCNTs suspension and silver nitration solution. PU/MWCNTs composites are made by solvent mixing method, and the electrical property of Ag nanoparticles encapsulated into the inside of MWCNT / PU composites are compared with those of MWCNT / PU composites. The electrical property of Ag nanoparticles encapsulated into the inside of MWCNT / PU are measured by Dielectronic Analyzer (DEA) , and the electrical property has increase 100 times better than the those of MWCNT/PU composites. |
