Colour changing material: A challenge to the colour industry

Polymer Opals

Wired.co.uk reports on a new material developed at Cambridge University NanoPhotonics Centre which changes colour depending on how it is manipulated or s t r e t c h e d. This is achieved by “printing” 200 nanometre spheres, whilst modulating the voltage during the process. Advanced Engineering Materials has a more detailed background to the technology.

How will these materials be assessed using current methods in QC e.g. lightboxes and spectrophotometers? A future challenge for the colour industry…
