NANOCOMPOSITE MULTI-LAYERED THIN FILM CONTAINING SUPER-PARAMAGNETIC NANO PARTICLES, AND A PRODUCING METHOD THEREOF

摘要

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.;COPYRIGHT KIPO 2012
