Title: MAGNETIC NANO-PARTICLE HAVING IMPROVED DISPERSIBILITY IN FLUORINE-BASED SOLVENT AND METHOD FOR PRODUCING SAME
Abstract:
The present invention provides a fluorine-based-solvent-soluble magnetic nano-particle which includes a magnetic nano-crystal core and a ligand shell containing a fluorinated hydrocarbon-based or fluorinated carbon-based carboxylic acid represented by chemical formula CF3-(CF2)x-(CH2)y-COOH. In addition, the present invention provides a method for producing a fluorine-based-solvent-soluble magnetic nano-particle, the method comprising: a first step of producing a second magnetic nano-particle, which includes a magnetic nano-particle core and a ligand shell containing a fluorinated hydrocarbon-based or fluorinated carbon-based carboxylic acid represented by chemical formula CF3-(CF2)x-(CH2)y-COOH, by adding and reacting a fluorine-based solvent, containing a fluorinated hydrocarbon-based or fluorinated carbon-based carboxylic acid represented by chemical formula CF3-(CF2)x-(CH2)y-COOH, in a solution in which a first magnetic nano-particle coated with fatty acid is dispersed in an organic solvent; and a second step of collecting the second magnetic nano-particle that has moved to a fluorine-based solvent layer.
