Cheap And Fully Recyclable Lighting Material
The new super material called “graphene” is being developed by scientists from the U.S. and Sweden. Graphene used as an alternative material instead of conventional metal electrodes to make lighting component called light-emitting electrochemical cell (LEC) that is better than LEDs or OLEDs (Organic LED technology).
The LEC transparent electrode made of the carbon material graphene. Graphene has many advantages compared with ordinary lighting component that used in LEDs or OLEDs because is a fully recyclable lighting component, its 100% recyclable. Graphene can be created from liquid solutions so that it can be printed. Because can be reprinted it will automatically cut production costs or much less expensive and more efficient than OLEDs when create en masse.
Graphene consists of a single layer of carbon atoms with the properties of a good electronic materials such as high conductivity, virtually transparent, and can be produced as a solution in the -m of graphene oxide.
Researchers says that graphene paves the way – cheap production of plastic-based lighting, perhaps – the first time. It could be used to create glowing wallpaper made out of plastic like LEDs/OLEDs but has several advantages. Even though we already know that LEDs is very efficient, long-lasting but it’s expensive to produce. In addition LEDs was made of transparent electrode consists of the metal alloy indium tin oxide that is rare and expensive material. Indium is also have a weakness that is complicated to recyclable.
