Polyaniline–maghemite based dispersion: electrical, magnetic properties and their cytotoxicity

Popis výsledku v původním jazyce

Polyaniline–maghemite (PANI–γ-Fe2O3) based dispersion has been prepared in several steps. First, iron oxide nanoparticles with mixed-phase composition were synthesized by coprecipitation method. Second, obtained particles were transformed to γ-Fe2O3 with sodium hypochlorite. Finally, aniline hydrochloride was in-situ polymerized with ammonium peroxydisulfate in the presence of γ-Fe2O3 particles in aqueous solution of poly(N-vinylpyrrolidone). Colloidal PANI–γ-Fe2O3 hybrid particles have average size of about 350 nm and the dispersity between 0.12 and 0.38. Hybrid dispersions with different concentration of conducting phase were characterized by electron microscopy, dynamic light scattering, UV–vis spectroscopy, thermogravimetric analysis, magnetization curve and conductivity measurements, as well as dielectric spectroscopy. Cytotoxicity on mouse embryonic fibroblast cell of PANI–γ-Fe2O3 colloid has been investigated.
