<description>Effects of the conditions of the microemulsion preparation on the properties of Fe3O4 nanoparticles
Nguyen, Thai Ha; Nguyen, Hoang Hai; Nguyen, Hoang Luong; Nguyen, Chau; Huynh, Dang Chinh
Fe3O4 nanoparticles have been prepared by the microemulsion technique with water as&#13;
the aqueous phase, n-hexane as the oil phase and Span 80 as the surfactant. The reaction occurred&#13;
under air, N2 or high temperature and high pressure atmosphere. Particle size can be controlled by&#13;
the concentration of the reactants dissolved in water, the ratio of water/surfactant and the&#13;
atmospheric conditions. The particle size is of 6 - 20 nm. They are superparamagnetic with the&#13;
saturation magnetization of 50 emu/g. Functionalization of the particle surface has been carried out&#13;
by using a single layer of oleic acid for hydrophilic surface and double layer of oleic acid and&#13;
sodium dodecyl sulfate for hydrophilic surface to disperse them in non-aqueous and aqueous&#13;
solvents, respectively. Changing the conditions of the preparation affected to the properties of the&#13;
product. This technique showed advantages such as simple, small size particles, monodisperse&#13;
over the coprecipitation methods.
