In 2015, China led the world of mass production of annual capacity exceeds hundred to thousand tons of pristine graphene or graphene oxides powders or pre-dispersed pastes, and million square meters of CVD graphene films.Mass production of few layer (< 10 layers) and even single layer products are in large volume shipping.If the demand increases, it is possible to scale up to >10,000 tons annual production capacity by using single production line.This indicates that the large scale industrial productions of any polycrystalline graphenes are completed in China.
