Graphene is a single layer of graphite; an array of carbon atoms arranged in a hexagonal honeycomb lattice. .It’s hard to describe the properties of graphene without a heavy dependence on superlatives. At just one atom thick, it’s a million times thinner than a human hair, 200 times stronger than steel. It’s a better conductor of electricity than copper. In fact, it’s better than anything at conducting heat and electricity. It’s extremely flexible–bendable and stretchable–impermeable to water, transparent, completely organic, affordable…and that’s just for starters. Graphene is expected to enable energy storage devices with several new features that do not exist in the current technology. Nanotech Energy is working on converting this dream into a reality.
THE POWER TO CHANGE THE WORLD
Nanotech Scientific Board Members, Richard Kaner, PhD, and Maher El-Kady, PhD, have developed a scalable way to create graphene supercapacitors. Here, they explain the wonders of graphene and their game-changing discovery.
Similar to conventional printing, printed electronics applies ink onto paper, plastic or other substrates. Because electrical conductors are essential for printed electronic devices, significant efforts by Nanotech Energy have been devoted to the development of functional conductive materials. Graphene and graphene-based materials have superb electronic structure and therefore can provide excellent properties including high chemical and thermal stability as well as outstanding electrical conductivity.
Applications include thin film transistors, transparent conducting electrodes, sensors, RFIDs, etc. Nanotech Energy’s proprietary graphene inks can also provide high specific surface area, which will be highly beneficial for printed batteries and supercapacitors.
Since it was discovered more than a decade ago, graphene has attracted interest thanks to its unusual electronic, optical, mechanical and electrical properties which opens the door for a wide range of technological applications. However, the production of functional graphene materials on a large scale is still challenging but Nanotech Energy is about to change this game.
Nanotech Energy offers graphene oxide and graphene products in different formulations that are designed to be customized for every kind of use. Because of this, Nanotech Energy’s graphene products have the potential to revolutionize graphene industry with applications in batteries, transparent conducting electrodes, functional inks, flexible displays, antistatic coatings, RFID antennas to name but a few.
HOW WE MAKE GRAPHENE
To extract graphene from graphite, Nanotech Energy uses simple chemical compounds that insert oxygen atoms between the layers of graphene, converting it to graphite oxide which falls apart in water forming individual graphene oxide sheets. These sheets can be converted back to graphene using proprietary chemical, hydrothermal and photothermal methods.
