China Focus: Graphene industry gathers pace in China
NANNING, Aug. 23 (Xinhua) — The new material graphene has been developing fast in China, increasingly being used in a variety of areas. At a graphene forum in south China’s Guangxi Zhuang Autonomous Region on Monday, Feng Guanping presented temperature-controlled leg guards, scarves and cushions. All the items had a heatable #graphene film inside, which can generate heat for up to six hours. “The temperatures can also be changed artificially,” said Feng, president of Shenzhen Grahope New Materials Technologies. Graphene is the world’s strongest and lightest material; a single layer of graphene is just 0.335 nanometers thick and can conduct heat and electricity. In China, the material is already a big industry, with more than 500 companies specializing in different graphene-related products. Smartphones, for example, can easily get overheated when people make long calls or play games, but the problem has basically been solved with the application of graphene. A company in eastern China’s Changzhou has developed a heat conducting material from graphene, which is being used in smartphnes. The invention helped increase the company’s revenue from 6 million yuan (904,600 U.S. dollars) to 200 million yuan within three years.
