Abstract
One embodiment of the present disclosure provides a method for producing an angle-independent colloidal particles-based structure, the method having: preparing two or more types of hollow colloidal particles, wherein the types are distinguished based on a size of the hollow colloidal particles thereof, wherein the types have different particle sizes; and dispersing the at least two types of hollow colloidal particles to produce an amorphous structure, wherein the amorphous structure realizes the same color independently of an angle of an incident light thereto.
Claims11
A method for producing a colloidal particle-based structure, the method comprising:
- preparing first and second hollow colloidal particles, wherein the first hollow colloidal particles are of a different particle size from the second hollow colloidal particles;
- dispersing the prepared first and second hollow colloidal particles to produce an amorphous structure, wherein the amorphous structure has a same structural color independent of an angle of an incident light thereto;
- and
- treating the amorphous structure with a polymer or an inorganic material to fill gaps between the first and second particles.
A method for producing a colloidal particle-based structure, the method comprising:
