Structure and physical properties of layered ferrofluids
Iranian Journal of Physics Research
We have successfully synthesised and studied the bilayer ferrofluids with sodium oleate C18H33O2-Na+ as the first layer and sodium dodecyle sulfate C12H25Na+SO-4 (SDS) as the second layer surfactants. The solid phase of the ferromagnetic colloidal system was formed based on quick chemical growth. The adsorption of oleate molecule on the surface of the solid solution has been investigated by IR spectroscopy. The XRD analysis of the oxides and titration by KMnO4 show that the closestdoaj:3cdd73a3265c42ea91a53d3f68d15ac8 fatcat:giytp6y6fneldhgwxnc4h4gxxu
