Abstract
Ferrofluidi su koloidne suspenzije magnetnih nanočestica u tekućem mediju koje reagiraju na primijenjeno vanjsko magnetsko polje. Magnetne čestice se lako mogu slijepiti jedna s drugom što se sprječava korištenjem surfaktanata koji oko čestica stvaraju nabijene slojeve koji se onda međusobno odbijaju, tj. kada čestice dođu vrlo blizu jedna drugoj, neće doći do njihove aglomeracije nego će se istovrsni naboji odbiti. Korištenjem surfaktanata se osigurava proizvodnja stabilnih suspenzija. Kao magnetne čestice najčešće se koriste željezovi (ΙΙΙ) oksidi (Fe 3 O 4 ) odnosno magnetit. Ove metalne čestice se lako proizvode i imaju visoko magnetsko zasićenje. Zbog dobre reakcije na magnetsko polje, ferrofluidi se koriste u različitim područjima. Služe kao brtve, pomažu ciljanu aplikaciju lijekova u organizmu bez velikih nuspojava, smanjuju neželjene vibracije i zagrijavanje u snažnim zvučnicima. U ovom radu su opisane tehnike priprave i aplikacije ferrofluida.
Abstract (english)
Ferrofluids are colloidal suspensions of magnetic nanoparticles in a liquid carrier that react to an external magnetic field. Due to their small dimensions, magnetic nanoparticles can agglomerate easily and this can be prevented by the use of surfactants. Surfactants form a charged layer around nanoparticles and two same charged layers repulse each other. The use of surfactants ensures the production of stable ferrofluids. The most commonly used magnetic nanoparticles are iron (ΙΙΙ) oxides, Fe 3 O 4 (magnetite), due to their easy production and high magnetic saturation. Ferrofluids are widely used because of their great reaction to an external magnetic field. They act as seals in rotating shafts, help in targeted drug delivery in the organism while minimizing side effects, reduce unwanted vibrations and heating in loud speakers. Methods for the production and application of ferrofluids are described in this paper.
