    摘要: A ferrofluid composition consists of organic solvent or solvents to be used as liquid carriers, a charge-transfer complex or complexes for imparting electrical conductivity to the composition, fine particles of ferromagnetic material and additives for stably dispersing the aforesaid fine particles of ferromagnetic material into the organic solvent(s). According to this ferrofluid composition electrical conductivity of the fluid is given by the charge-transfer complex, which enhances the electrical conductivity, that is, functions to prevent electrification from occurring. The charge-transfer complex is dissolved, solubilized or dispersed in the carrier either by itself or by the aid of any additives. The ferromagnetic particles act to adsorb the additives and disperse them stably in the carrier and thus contribute to imparting magnetic properties to the carrier.
