Preparation of a Ferrofluid Using Cyclodextrin and Magnetite

Abstract

A ferrofluid has been obtained from magnetite and β-cyclodextrin, with the formation of an inclusion complex. The magnetite and β-cyclodextrin complex was characterized by FTIR spectroscopy, X-ray diffraction, thermal analysis (TG/DTA), transmission electron microscopy (TEM) and atomic absorption spectroscopy. As far as we know, this is the first report on an inclusion compound between a metal oxide and cyclodextrins.
