Abstract
Provided is a method for in-situ coating a substrate or matrix with magnetic metal nanoparticles. A metal salt, which may be organic or inorganic, is introduced into a solution of liquid polyol. In the presence of mechanical stirring and heat, a reduction process occurs wherein the magnetic metal nanoparticles precipitate out of solution and deposit or attach to one or more surfaces of the substrate. The concentration of reaction precursors, combined with the polyol, may be varied to control the size and shape of the magnetic nanoparticles.
