Özet

This study reports the refflux synthesis and dielectrical characterization of caffeic acid coated magnetite (Fe3O4) nanoparticles. Rietveld refinement confirmed the single phase product formation with the average crystallite size of 11.4 nm by Scherrer Formula. The coating of caffeic acid on the surface Fe3O4 nanoparticles was monitored by Fourier transform infrared spectroscopy, the interaction being via bridging oxygens of the carboxylate and the nanoparticle surface. ac/dc conductivity and dielectric analyses of product revealed semiconductor characteristics varying with temperature. ac conductivity increases regularly with temperature and do not show frequency-dependent behavior particularly at lower frequency regime whereas it exhibits a significant temperature dependent behavior at medium frequencies and at higher temperatures.
