New tech to make graphene,

Graphene new tech,

Graphene super strong material the miracle material can be used in almost anything and a lot of industries looking forward to using it ,Graphene is the world’s thinnest material at just a single atom thick, or one-million times thinner than a human hair, but is 200 times stronger than steel and conducts heat and electricity better than copper and it’s flexible, light and able to conduct heat and electricity better than most other materials out there, and have high-tech uses from integrated circuits, bendable mobile phone screens to prosthetic skin able to provide sensation. In fact, the only reason it hasn’t already revolutionized our energy, medical, and manufacturing industries are that it’s remained prohibitively expensive.
 Glasgow University’s research has discovered a way to produce large sheets of graphene with the same type of cheap copper used to manufacture lithium-ion batteries found in household appliances.

Dr Ravinder Dahiya, who led the university team working on the research, said: “The commercially-available copper we used in our process retails for around one dollar per square metre, compared to around $115 for a similar amount of the copper currently used in graphene production.
“This more expensive form of copper often required preparation before it can be used, adding further to the cost of the process.

“Our process produces high-quality graphene at low cost, taking us one step closer to creating affordable new electronic devices with a wide range of applications, from the smart cities of the future to mobile healthcare.”
The commercially available ultra-smooth Cu foils (which are generally used in Lithium-ion batteries) can help to open new avenues for large area device applications with the improved quality of the graphene films. We studied the synthesis of graphene on commercially available smooth Cu foils and we provided a detailed comparison between the graphene synthesized on ultra-smooth Cu foils and the one synthesized on the standard Cu foils in terms of structural, electrical and optical properties. We observed a stark improvement in the electrical performance of the transistors realized on our graphene films. Then, to demonstrate the advantage of high-quality graphene films from ultra-smooth Cu foils, we fabricated 400 cm2 flexible graphene electrodes and enlarged 160 times the previously reported (2.5 cm2) supercapacitor structure. To show the promises of our graphene films in electro-optic devices, we tested and compared the effects of graphene quality in large area supercapacitors. We anticipate that usage of commercially available ultra-smooth Cu foils for large area graphene growth would lead to higher performance devices especially for optical and electronic applications where low device variations are desired.
