How to get more bang for your buck with applied graphene materials
Posted October 17, 2018 06:18:16 The idea of graphene is that it can be used as a thin film of materials, such as an insulating layer, to form a protective layer on surfaces.
In a research paper published in the journal ACS Applied Materials & Interfaces, researchers describe the use of graphene to create a new material that has properties such as strength, ductility and a high surface area for applications in aerospace.
The researchers say that the use is a bit different from the traditional way of making applications of graphene, which involves forming a thin layer of the material in layers, often by coating a metal with an insulator.
The researchers say this is a way to reduce the amount of material that needs to be made and also to reduce cost by making the graphene layers in the same layer as the metal.
“There’s no reason to make the graphene layer as thin as the thin film,” said lead author Martina Marietta, an assistant professor of mechanical engineering at the University of California, Berkeley.
“We’ve come up with a material that can be made of a sheet of graphene and we can make the sheets as thin, which means the sheets can be layered in the way that you’d make the film for films.”
This is not the same as making a thin sheet of a metal and coating it with a layer of silicon, which you don’t want to do because it would create a lot of problems.
“We found that the material has a very good mechanical performance and we found that it has a good ductility.
We found that if you make the material with this ductility, it’s a lot less prone to breaking than if you do it by coating it in silicon.”
To make the new material, the researchers used a process known as chemical vapor deposition, or CVD.
They then heated the graphene and applied a thin coating of aluminum oxide to it.
The aluminum oxide melted, forming a layer that was then applied to a piece of copper.
The coating then dried, forming the graphene, and the material was deposited on a sheet.
“If you use aluminum oxide as a coating, it will not work because the aluminum oxide does not adhere to the graphene,” Mariettas said.
“But this coating is very strong, so we applied it to a copper layer, and it was very stable, which is what we wanted.”
The material is very conductive.
If you just use it for insulation, the conductivity drops.
So, we didn’t use it because it doesn’t hold a lot, but because it holds a lot.
“Because of the strong conductivity, we could do the coating layer in layers,” Mariatas said, adding that she and her colleagues would like to eventually test the material on metals and ceramics.
The material has the potential to be used for applications ranging from insulating fabrics, to a material for use in flexible sensors, and to conductive coatings.
