Graphene has been touted for the last few years as the next big thing in electronics. Potentially replacing copper and silicon in devices and promising to provide more energy efficient, faster charging batteries, the material has so far been limited by an inability to be mass produced. However, researchers have found a way to make a whole lot of graphene quickly and cheaply, which means we could see big improvements in everything from environment sensors for detecting pollution levels to OLED lighting to energy storage.
