UNIVERSITY of Sheffield scientists have developed a new material which could be used as anti-counterfeit devices on passports or banknotes.
The pigment-free intensely coloured polymer materials are said to be difficult to copy because of the complex chemistry behind them – making them ideal for use on passports and cash to avoid criminals trying to clone them.
Dr Andrew Parnell, from The University of Sheffield’s Department of Physics and Astronomy, said: “Our aim was to mimic the wonderful and funky coloured patterns found in nature, such as peacock feathers.
“We now have a painter’s palette of colours that we can choose from, using just two polymers to do this.
“We think these materials have huge potential to be used commercially.”
