This week in ceramic news, researchers at Missouri University have developed a potentially biodegradable screen layer for cell phones.
“People have shown that different components can be biodegradable, but the active layer so far was not shown to be biodegradable,” said Suchi Guha, physics professor and lead researcher. Current organic displays (or OLEDs) are made up of a light-emitting layer placed between two electrodes. These displays can be more power-efficient, as well as thinner and more compact. The active light-emitting layer, made out of organic polymers, is not biodegradable. But now it may be. Guha and his team, in collaboration with researchers in Brazil, used peptide nanotubes as scaffolding along with the organic polymers. Though it may not be fully biodegradable, it reportedly could become up to 80-85% degradable in the future with the use of the nanotubes.
