ElectricalGiven its excellent mechanical and electronic properties, graphene is expected to play a critical role in the progress of printed electronics.
FlexibleThin, flexible, low-cost and environmentally friendly – this is just a snapshot of what printed electronics can offer.
PotentialThe rise of this technology can be ascribed to its potential in providing cost-effective solutions to large-area electronic devices at a fraction of the cost of traditional semiconductor technology.
Nanotech Energy’s research and the market for printed electronics is rapidly growing with promising applications in smart packaging, organic solar cells, wearable electronics, and electronic papers.
Nanotech Energy has developed a simple, yet effective, method for the direct laser writing of graphene circuits that are flexible, conductive and suitable for the next generation of flexible electronics. Devices of any shapes and structures can be printed within minutes.
Printed Electronics Market
The overall printed electronics market is estimated to reach USD 13.6 billion by 2023 from USD 6.8 billion in 2018.
Supercapacitors are attractive energy storage devices with the ability to recharge in seconds rather than hours like traditional lithium-ion batteries.
Supercapacitors are also maintenance free and can be used for up to a million charge/discharge cycles. Their high power density and excellent low temperature performance have made them the technology of choice for back-up power, cold starting, flash cameras, and regenerative braking. They also play an important role in the progress of hybrid and electric vehicles.
However, the low energy density of current supercapacitors is the main impediment to realizing the full commercial potential of this technology.
This has triggered tremendous research efforts on Nanotech Energy’s part in order to develop new electrode materials that are capable of providing a huge amount of energy in a short period of time.
Earliest Graphene Patent
Nanotech Energy is backed by researchers who are highly experienced in this field and are at the forefront of this cutting edge technology. With a research experience of over 30 years our team has developed a wide range of nanoscale materials having the potential to change everything from conductive polymers, carbon electronics to water filtration and superhard materials. Filed in May 2002, our research team at UCLA holds one of the earliest patents on making graphene.
What is Reduced Graphene Oxide?
Since the graphene industry is growing very rapidly, it is important to distinguish between different graphene products currently available in the market.
The first pieces of single and few-layer graphene nanosheets were obtained through the exfoliation of bulk graphite using scotch tape. Although this route leads to non-defective pristine graphene, its low yield makes it unpractical for large scale. Mass production of graphene was made possible through chemical exfoliation of graphite.
This can be achieved by direct exfoliation of graphite in a liquid, with or without a surfactant or by inserting chemical species between graphite interlayers to weaken the forces holding them together, thus facilitating their exfoliation. While these techniques are widely used for the production of graphene with low defects, the product is usually thick and is often referred to as nanoplatelets. These nanoplatelets are suitable for applications requiring high electrical and thermal conductivity but their low surface area and poor dispersibility in various solvents make their further processing difficult.
Our product, developed by Nanotech Energy, involves the extraction of high-quality graphene from graphite using a simple and efficient chemical process. By introducing oxygen atoms between the layers of graphene, we convert the graphite into individual sheets of graphene oxide.
These graphene oxide sheets can then be transformed back into graphene (also known as reduced graphene oxide) through our proprietary chemical, thermal and photothermal processes. The reduction process transforms graphene oxide into reduced graphene oxide, where the oxygen groups are significantly reduced or eliminated, leading to the restoration of the pristine carbon network of graphene. As a result, our product consists of truly single-layer graphene sheets with a high level of purity and low oxygen content and is effective at preventing the restacking of individual graphene sheets.
One of the notable features of our product is its ease of processing. Our reduced graphene oxide can be easily dispersed in solvents, allowing for convenient integration into various applications and manufacturing processes.
