MONTOYA, P. et al. Effect of the Incorporation of Magnetite Particles in Polypyrrol Films. Port. Electrochim. Acta [online]. 2009, vol.27, n.3, pp.337-344. ISSN 0872-1904.

The electrical properties of conducting polymers make them useful materials in a large number of technological applications. In the last decade, it has been showed an important effect on the properties of the conducting polymer when iron oxide particles are incorporated into the conductive matrix. In the present study, films of polypyrrole were synthesized in the presence of magnetite particles. The effect of the magnetite particles on the structure of the polymer matrix was determined using Raman spectroscopy and mass variations at different concentrations of Fe₃O₄ incorporated into the conducting matrix were also calculated by means of quartz crystal microbalance.
