ENCAPSULATION OF MAGNETIC gFe2O3 NANOPARTICLES INTO POLYPYRROLE MATRIX
D.-V. BREZOI


Abstract. Nanocomposites with magnetic nanosized cores encapsulated into polymer matrix have some special applications: information storage, ferrofluids, high-gradient magnetic separation and medical diagnosis. The
γFe2O3-PPy nanocomposite was prepared by the polymerization of pyrrole on the γFe2O3 nanoparticles. FTIR, XRD, EPMA, TEM experiments showed that the polypyrrole partially covers the γFe2O3 nanoparticles.
