Abstract
Articles of wear comprises iron oxide colloidal nanocrystals arranged within chains are described. The chains of nanocrystals display a color that is determined by a strength of a magnetic field applied to the chains of nanocrystals, wherein the color is maintained when the magnetic field is removed.
Claims24
An apparatus for manipulating a color displayed by an article of footwear or apparel comprising iron oxide colloidal nanocrystals arranged within chains, the apparatus comprising:
- a platform comprising a substantially flat surface;
- and
- a pulsating electromagnet configured to switch between generating a rapidly fluctuating magnetic field and a non-fluctuating magnetic field.
An apparatus for manipulating a color displayed by an article of footwear or apparel comprising iron oxide colloidal nanocrystals arranged within chains, the apparatus comprising:
- a platform configured to support the material or article of footwear or apparel;
- and
- a magnetic field source configured to create transient currents in the chains of nanocrystals and/or to produce a magnetic field that is tunable to control the color displayed by the material or article of footwear or apparel.
An apparatus for manipulating a color displayed by an article of footwear or apparel comprising iron oxide colloidal nanocrystals arranged within chains, the apparatus comprising:
- a platform;
- and
- a magnetic field source comprising pulsating electromagnets;
- wherein the magnetic field source is arranged so that a magnetic field produced by the magnetic field source extends across a surface of the platform.
