heal.abstract |
A new poly(ester-b-ether) copolymer filled with magnetic gamma-Fe2O3 nanoparticles of low concentration (0.1 and 0.3 wt%) has been synthesized, with poly(ethylene terephthalate) (PET) as a rigid segment and poly(tetraoxymethylene) (PTMO) as the flexible segment at the ratio of 50 wt%. The filler was used in the form of suspension or solid powder. The dielectric spectroscopy results for these materials, in a wide range of frequencies and temperatures, are presented and compared with similar results for a pure polymeric matrix. Two relaxation processes, alpha and beta, have been observed clearly in all samples at about 253 K and 163 K, respectively. The a process was shifted towards the lower temperatures as the nanoparticle content increased, while the beta-relaxation was unaffected by the doping. The interfacial polarization effect was observed in the samples with nanoparticles, less pronounced for the larger nanoparticles. (c) 2006 Elsevier B.V. All rights reserved. |
