ZheJiang University researchers in China demonstrate graphene aerogel by placing the extremely light substance on a flower. Professor Gao Chao created this by using a new freeze-drying method that involved freeze-drying solutions of carbon nanotubes and graphene to form a carbon sponge that can be arbitrarily adjusted to any shape. The final result is a very strong and extremely elastic material that can also absorb up to 900 times its own weight in oil – one gram of aerogel can absorb up to 68.8 grams of organics per second, making it perfect for mopping up oil spills at sea.
