Title: On the possibility to use short chain length mono-carboxylic acids for stabilization of magnetic fluids
Published In: Journal of Magnetism and Magnetic Materials, Vol. 311, No. 1, pp. 6-9
Description: Short chain length mono-carboxylic acids (lauric and myristic acids) are used to coat magnetite nanoparticles in non-polar organic liquids, which results in highly stable magnetic fluids. The new fluids are compared with classical organic fluids stabilized by oleic acid (OA). Magnetic granulometry and small-angle neutron scattering (polarized mode) reveal a great difference in the particle size distribution function for the studied magnetic fluids, particularly a decrease in the characteristic particle radius of magnetite when lauric and myristic acids are used instead of OA.
