Strongly polar magnetic fluids with Fe/sub 3/O/sub 4/ and CoFe/sub 2/O/sub 4/ nanoparticles

D. Bica Oana Marinică Floriana D. Stoian Daniela Susan-Resiga L. Vékás

The paper presents experimental results concerning the chemical synthesis of Fe/sub 3/O/sub 4/ and CoFe/sub 2/O/sub 4/ magnetic nanoparticles, as well as the stabilization/dispersion mechanisms applied to obtain strongly polar magnetic fluids on water and pentanol carriers. The colloidal stability of samples was analyzed through investigations of the magnetic and magnetorheological behaviour of samples.

Clustering in Water Based Magnetic Nanofluids: Investigations by Light Scattering Methods

AIP conference proceedings (2010)

Vlad Socoliuc Elena-Alina Moacă Camelia Podaru Andreea Dobra Camelia Daia

Nanosized magnetite particles, with mean physical diameter of about 7 nm, obtained by chemical coprecipitation procedure were dispersed in water carrier by applying sterical stabilization of particles in order to prevent their aggregation and to ensure colloidal stability of the systems. Different chain length (C12, C14, C18) carboxylic acids (lauric (LA), myristic (MA) and oleic (OA)) were used for double layer coating of magnetite nanoparticles. Structural and magnetic properties were investigated by electron microscopy (TEM), dynamical and static light scattering (DLS, SLS) and magnetometry (VSM) to evaluate the role of chain length and of the saturated/unsaturated nature of surfactant layers. Also investigated were two water based magnetic nanocomposites obtained by encapsulating the magnetic nanoparticles in polymers with different functional properties.

Magnetic nanocomposites obtained using high evaporation rate magnetic nanofluids

International Journal of Nanomanufacturing (2007)

N. Crainic Doina Bica António Torres Marques Nicolae Popa P. J. Nóvoa

In this paper, we study the influence of the addition of small amounts of nanomagnetic fluids in resins, some specific properties of these fluids and the possibility to produce a new category of magnetisable nanocomposite materials. The research was focused on the compatibility between the various types of nanomagnetic fluids and resins. Samples were prepared varying the resins, carrier liquids and volume fraction of magnetic nanoparticles. The polymerisation process of nanocomposites was investigated under the influence of applied magnetic field. Results of investigations presented in this paper refer to the microstructure of the samples (optical and/or electronic microscopy), and to the mechanical properties corresponding to different preparation methods (three points bending test, elastic properties, gel time determination).

SYNTHESIS AND CHARACTERIZATION OF NANOSTRUCTURED POLYPYRROLE-MAGNETIC PARTICLES HYBRID MATERIAL

Rodica Turcu D. Bica L. Vékás N. Aldea D. Macovei

We report the synthesis and characterization of the nanocomposites obtained by the combination between a well-known conducting polymer polypyrrole (PPY) and magnetic nanoparticles Fe3O4. The properties of the composites were investigated by TEM, X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), FTIR spectroscopy, d.c. conductivity and magnetization measurements.
