PURPOSE: A nanocomposite multi-layered thin film containing super-paramagnetic nano particles, and a producing method thereof are provided to maximize the adsorption density of the nano particles by maintaining the magnetic property. CONSTITUTION: A nanocomposite multi-layered thin film containing super-paramagnetic nano particles includes a quartz or silicon substrate, a first polymer layer, and a first super-paramagnetic nano particle layer. The first polymer layer is located on the substrate, and includes functional groups with an unshared electron pair as end-groups. The first super-paramagnetic nano particle layer is located on the first polymer layer, and is stabilized by a compound having a halogen group as an end-group. The first polymer layer and the first super-paramagnetic nano particle layer are combined by the nucleophilic substitution reaction between an amino group and a bromine group in an inorganic solvent.

Abstract:
The present invention relates to a multifunctional material capable of reversible phase transfer via layer-by-layer assembly and a method for preparing the same. One or more layers are stacked on a material surface in a substrate or a particle form while the outermost layer is either a dendrimer or a polymer including an amine group, or a metal or metal oxide layer. According to the present invention, the multifunctional material has a high dispersion to an organic solvent and an aqueous solution, and is stable for the external environment. In addition, the density of the coated particles is significantly high.
