Abstract

Microstructural insight in some new ferrofluids was obtained using ferrophase size scanning. Two ferrofluids, were prepared: the oil-ferrofluid and kerosene-ferrofluid (the ferrophase being stabilized with oleic acid). The Atomic Force Microscopy was used to visualize and to measure the nanoparticle diameter and height – the 3-D imaging representing one of the main advantages of this scanning technique. Both 3-D and phase representations have been used. The transmission Electron Microscopy images have been also analyzed. The diameter distribution has been obtained. The chain and aggregates particles are related to the ferrofluid stability..
