Abstract
Provided is a method of printing a structural color. The method includes providing a first substrate, forming a layer of a composition for generating a structural color including magnetic nanoparticles and a curable material on the first substrate, applying a magnetic field to the layer of the composition for generating a structural color and exhibiting a structural color using a change in lattice spacing of a photonic crystal composed of magnetic nanoparticles depending on the magnetic field strength, and curing the layer of the composition for generating a structural color to fix the lattice spacing of the photonic crystal and to form a structural color printed layer.

A method of printing a structural color comprising:
- providing a first substrate;
- forming a layer of a composition for generating a structural color including magnetic nanoparticles and a curable material on the first substrate,
- applying a magnetic field to the layer of the composition for generating a structural color and exhibiting a structural color through a change in lattice spacing of a photonic crystal composed of magnetic nanoparticles depending on the magnetic field strength;
- and
- curing the layer of the composition for generating a structural color to fix the lattice spacing of the photonic crystal and to form a structural color printed layer.
A method of generating a structural color comprising fixing an aligned structure of magnetic nanoparticles in a medium to diffract light due to the aligned structure and to generate the structural color,
- wherein the aligned structure is produced in a liquid medium, the liquid medium is converted into a solid medium, and thus the aligned structure is fixed.
A method of producing a structural color comprising:
- tuning an aligned structure by aligning magnetic nanoparticles containing a superparamagnetic material in a photocurable material;
- and
- fixing the aligned structure by curing the photocurable material,
- wherein the tuning and the fixing are repeated to perform multi-color patterning.
