Peva, a new polymer material, could revolutionise the way materials are manufactured.
It is being developed by scientists at the University of California, Berkeley, and is based on graphene.
“The key is that graphene is an excellent surface that can be melted and then bonded to any desired material,” said Professor Andrew A. Gendron from the Department of Materials Science and Engineering.
Peva was invented by a group of scientists led by Professor Gendro at UC Berkeley, led by Prof. Daniel S. Mazzola. “
Graphene is the only one that is flexible, robust, and conductive, so we’re able to make a material that has a high conductivity, which is the most important thing for materials in the world.”

“We wanted to make material that would be durable and that would conduct electricity at high speeds, so that it could be used in electronics and solar panels,” Professor Gendingron said.
“Peva is an extremely high conductive material, and this is because it has these extremely thin sheets, which are about 30 nanometers thick. “
“When you melt a layer of Peva on a sheet of graphene, the heat generated by the melting of the Peva will generate electrical current, and that current can be transmitted through the graphene.” “
The researchers have used this process to make conductive polymer polymers that can conduct electricity. “

Polypeva is a single layer of graphene that is sandwiched between two layers of polycarbonate.
The graphene layer is about 10 nanometers wide, and the graphene layer in the centre of the polycarbonic layer is a thin layer of silicon carbide.
The researchers also used this thin layer to make polypeavarones, which have an outer layer of polypeacrylic which is then sandwiched in between two thinner layers of silicon.
The polypevinol layer is made up of two layers.
“Polypeva has these high conductivities, so it’s really important that you have conductive polypevins in the material,” Professor Mazzana said.
Peva has a wide range of properties.
Professor Genderron said it was important to have materials that could conduct electricity and be conductive at high temperatures.
“You need a material with high conductances, and if you can make it conductive and conduct well, then you have an excellent material for high-temperature applications,” he said.
PolyPEVA is the second new polymer to be developed by the Berkeley group.
The first, which was developed by Drs.
David Miller and Michael J. Minkler, was made by Dr. Miller’s lab at the National University of Singapore.
“That material is called polycarbonates, and I’m really happy that they’re making it, because that material is really well-suited for high temperature applications,” Professor Miller said.
Dr. Minkingler said the new material had a high electrical conductivity and conductivity of 2.6 per cent, and could conduct about 50 milliwatts of current.
“This material is the best of the best in terms of high conductance and high conductability, and these are the two main things that are important,” he added.
“If you can have these two properties, then if you want to do high-voltage applications in electronics or solar cells, then that material will perform very well.”
“PolyPEVA has all of the properties that we want in a polymer, and has been designed to perform these very well,” Professor Soneida said.
The Berkeley team also made a high-strength polycarbonated composite material, called polyvinyl acetate, which had a conductivity as high as 3.2 per cent and was also extremely strong.
Polyvinylacetate, as well as the polypevalone that is being made by the researchers, has been made in the lab, and will be used to make other polymer materials in a few years.
“I think we have shown that the materials can be made using a process that has been well-designed,” Professor F.J. Hoch said.
Prof. Mankner said the materials were able to perform well at temperatures of between 500 and 750 degrees Celsius.
“There’s a very important difference in the properties of these materials, and they have to be very, very robust to do that,” he explained.
Professor Swayze said the material was an important step forward in materials research.
“These materials are extremely conductive to this point, and very robust, which we’ve shown is really important,” she said.
