Environmentally friendly way to make coloured plastics.

WASHINGTON DC, US: Long before humans figured out how to create colours, nature had already perfected the process – for example stunning, bright butterfly wings of many different hues. Now scientists are tapping into those secrets to develop a more environmentally friendly way to make coloured plastics. Their paper on using structure - or the shapes and architectures of materials - rather than dyes, to produce colour appears in the ACS journal Nano Letters.

Researcher N Asger Mortensen, Anders Kristensen and colleagues point out that currently, plastic manufacturers add pigments to their products. That gives them the range of colours customers have come to expect in everything from toys to tools. But these additional ingredients add to the growing waste stream of plastics manufacturing and make it difficult to recycle products. To come up with a more eco-friendly alternative, Mortensen’s team turned to highly advanced materials that can be made to appear in different colours - purely by designing their surface structures at the nanoscopic level.

They layered materials, including ultrathin, nano-sized aluminum disks, in a way that manipulates light and creates a new kind of coloured surface. To protect it from damage, the scientists topped it off with a scratch-resistant film. Using this method, they created a wide spectrum of colours that could be added to plastics.
