The Investigation of Polyethyleneimine Adsorption on Magnetite Nanoparticles by Spin Labels Technique
Adsorption of polyethyleneimine and 80% ethoxylated polyethyleneimine on the surface of magnetic nanoparticles (magnetite) in aqua medium is studied using spin labels technique. The technique has been adapted for adsorption study in magnetic dispersions. Stable nitroxide radicals covalently
bound to macromolecules were used as spin labels. The value of polymers adsorption on nanoparticles was calculated.
