Abstract
Methods of manipulating a color displayed by a transfer medium or substrate comprising iron oxide colloidal nanocrystals arranged within chains, wherein each chain of nanocrystals is encapsulated are described. The method includes (a) applying a magnetic field to the transfer medium or substrate to control the color displayed by the transfer medium or substrate; and (b) applying energy to at least some of the chains of nanocrystals at a level that destroys the encapsulation surrounding the chains of nanocrystals to which the energy is applied.

A method of manipulating a color displayed by a transfer medium or substrate comprising iron oxide colloidal nanocrystals arranged within chains, wherein each chain of nanocrystals is encapsulated, the method comprising:
- (a) applying a magnetic field to the transfer medium or substrate to control the color displayed by the transfer medium or substrate;
- (b) applying energy to at least some of the chains of nanocrystals at a level that destroys the encapsulation surrounding the chains of nanocrystals to which the energy is applied such that the nanocrystals are unable to adjust position within the chains of nanocrystals and within the transfer medium or substrate when the magnetic field is applied;
- and
- (c) applying the transfer medium or substrate to a material or article of wear to transfer the color to the material or article of wear.
A method of manipulating a color displayed by a raw material comprising iron oxide colloidal nanocrystals arranged within chains, wherein each chain of nanocrystals is encapsulated, the method comprising:
- (a) applying a magnetic field to the raw material;
- (b) applying energy to at least some of the chains of nanocrystals to soften materials within the raw material immediately surrounding the chains of nanocrystals to which the energy is applied;
- (c) adjusting a strength of the magnetic field to control the color displayed by the raw material;
- (d) applying additional energy to at least some of the chains of nanocrystals at a level that destroys the encapsulation surrounding the chains of nanocrystals to which the energy is applied such that the nanocrystals are unable to adjust position within the chains of nanocrystals and within the raw material when the magnetic field is applied;
- and
- (e) forming an article of wear from the raw material, wherein the raw material is manipulated prior to forming the article of wear.
A method of manipulating a color displayed by a transfer medium or substrate comprising iron oxide colloidal nanocrystals arranged within chains, wherein each chain of nanocrystals is encapsulated, the method comprising:
- (a) applying a magnetic field to the transfer medium or substrate;
- (b) applying energy to at least some of the chains of nanocrystals to soften materials within the transfer medium or substrate immediately surrounding the chains of nanocrystals to which the energy is applied;
- (c) adjusting a strength of the magnetic field to control the color displayed by the transfer medium or substrate;
- (d) applying additional energy to at least some of the chains of nanocrystals at a level that destroys the encapsulation surrounding the chains of nanocrystals to which the energy is applied such that the nanocrystals are unable to adjust position within the chains of nanocrystals and within the transfer medium or substrate when the magnetic field is applied;
- and
- (e) applying the transfer medium or substrate to a material or article of wear to transfer the color to the material or article of wear.
