A new method for low-cost production of graphene reduces medical costs
Researchers at the University of Glasgow in the United Kingdom and the University of Birken in Turkey have discovered a new way to produce large-area graphene at low cost, using inexpensive copper for the production of lithium batteries for household equipment. Under the leadership of Dr. Ravinder Dahiya, the research team produced large-area graphene 100 times cheaper than the current method.
Graphene is usually produced by CVD. The team used a similar process to create high-quality graphene, which is commonly used as the negative electrode for lithium batteries. The ultra-smooth surface of copper provides an excellent basis for the formation of graphene. By comparing with the old production methods, they found that the graphene produced by the new method has a significant improvement in the photoelectric performance of the transistor.
“The retail price of commercially available copper we use is about $1 per square meter, and the current price of copper used for graphene production is about $115,†Dahiya said. “This more expensive copper usually requires prefabrication. before you can use, thus further increasing the production costs. our approach can produce low-cost high-quality graphene can further create a more expensive electronic equipment applications, including the future of healthcare and smart cities. "For example, Dr. Dahiya the focus The restoration can take advantage of this technology. (Text / Yalin translation)
