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.
Claims19
An apparatus for manipulating a color displayed by an article of wear 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;
- wherein the substantially flat surface comprises a gap therein, and wherein the article of wear comprises a roll of textile that is unrolled proximate a first end of the platform, positioned adjacent the surface of the platform and the gap therein, and re-rolled proximate a second end of the platform.
An apparatus for manipulating a color displayed by a material or article comprising iron oxide colloidal nanocrystals arranged within chains, the apparatus comprising:
- a platform configured to support the material or article;
- 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;
- wherein the platform comprises a substantially flat surface having a gap formed therein, and wherein the material or article comprises a roll of textile that is unrolled proximate a first end of the platform, positioned adjacent the surface of the platform and the gap therein, and re-rolled proximate a second end of the platform.
An apparatus for manipulating a color displayed by a material or article 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, and wherein the material or article comprises a roll of textile that is unrolled proximate a first end of the platform, positioned adjacent the surface of the platform, and re-rolled proximate a second end of the platform.
