ANALYSIS DIELECTRIC RELAXATION IN NANOKOPOITE PET/CNT
Journal Title: Proceedings of Electrotechnical Institute Prace Instytutu Elektrotechniki - Year 2012, Vol 59, Issue 259
Abstract
The paper presents a stady by the FDS (Frequency Domain Spectroscopy) composite PET – polyethylene terephthalate and PEE – poly (ester-ether) with additives MWCNT – polyhedral subjects fluorinated carbon nanotubes modified functional groups or OC2H5NH2. Analysis of the results was performed using the Havriliak’a-Negami’ego. It was observed that doping nanostructure PEE MWCNT composite can significantly increase yhe time constant of the space charge and the polarizability of the material. And the introduction of the structure of the nanotube-modified OC2H5NH2 groups causes significant reduction in low-frequency relaxation time constant, which is likely to be associated with a merger uncompensated space charge of functionalized nanotubes. The results is a new chemical structure. Increasing concentraction of admixture of these structures has little effect on the relaxation processes. A similar effect is observable in the case of additives with fluorinated MWCNT.
