Graphene Ink Production Applications and BenefitsAugust 19, 2022
Graphene has recently gained a lot of popularity as it is the strongest and thinnest material known to man. It is more vital than steel, and a single strand can be so thin that it is almost invisible to the human eye. In general, graphene can be produced from natural or artificial graphite through chemical oxidation, reduction, or hydrocarbon gas reaction processes. There are various ways to create graphene ink; however, this article focuses on graphene ink production methods used for application in printed electronics and other fields such as textile dyeing and surface coating.
Graphene is a one-atom-thick graphite layer with unique properties and a host of potential applications. Graphene ink is produced by dissolving graphite in an appropriate solvent and applying the solution to a surface. The process is cost-effective, scalable, and eco-friendly. It can be utilized for paints, inks, coatings, and elastomers. Graphene ink production finds extensive application in electronics, battery electrodes, solar cells, sensors, conductive films, printed antennas, innovative packaging, and 3D printing, among others. This article presents an overview of the top graphene ink production applications with details about their benefits.
The production of graphene ink has seen a notable uptick in interest and adoption over the last few years. This is mainly due to the unique properties that graphene as a material offers when used with digital printing processes like sublimation and direct-to-fabric printing. In addition, the specific properties we see in most graphene production methods also lend themselves to being used with digital printing processes. Graphene’s ability to conduct electricity, transparency, and strength make it an ideal candidate for many digital textile applications. As a result of this increased adoption within the industry, we have seen many companies begin to offer their take on graphene ink production services or their own branded product as a finished end-product. If you are curious to understand more about how you can leverage graphene for your company or business, read on to learn about some of the top applications for graphene ink production and some benefits of using each one:
Printed Electronic Textiles
Electronic Textiles can be produced using graphene ink. This can include athletic fabrics that monitor performance, garments with embedded sensors that can be used in medical settings, or even more fashion-focused pieces. In the latter case, graphene enables greater design flexibility and added functionality that may not be possible with other fabrics. One of the most exciting but unrealized applications of graphene in printed materials is the concept of “smart clothing.” This intelligent clothing would be capable of sensing data about the environment around the wearer or their internal biometrics. In theory, these fabrics could connect to smartphones and other internet-connected devices to collect data, notifying the wearer of important information such as heart rate, steps taken, etc. Graphene has the potential to make this intelligent clothing a reality as one of its most exciting properties is its ability to conduct electricity.
Smart Wearable Technology
Innovative wearable technology integrates electronic devices with fabrics, clothing, or textiles. This can include the integration of touchscreens, computer chips, and even sensors within the material itself. This technology is to be integrated into many daily items such as clothing, wearable health tracking devices, or even hats and scarves. Graphene can be highly conductive, making it an ideal candidate for this type of wearable technology. It also allows it to be transparent, which enables it to be incorporated into fabrics like silk that are highly transparent.
3D Printing with Graphene Ink
One of the most exciting but unrealized applications of graphene in printed fabrics is the concept of “smart clothing.” This intelligent clothing would be capable of sensing data about the environment around the wearer or their internal biometrics. In theory, these fabrics could connect to smartphones and other internet-connected devices to collect data, notifying the wearer of important information such as heart rate, steps taken, etc. Graphene has the potential to make this intelligent clothing a reality as one of its most exciting properties is its ability to conduct electricity.
Graphene has been used in 3D printing applications to create conductive pathways within printed objects. This can be done by mixing graphene into the printing filament and printing with the graphene-infused filament or applying graphene-based inks to the printed object. Graphene may also be used to create increased strength in 3D printed objects. This could be done by mixing graphene into the print resin or coating the printed thing with graphene-based ink. Graphene could also be applied as a coating on the printed object after publication. Graphene applied to the object’s surface could be used to create a conductive pathway between the printed objects and other devices.
Another way to produce printed objects with graphene ink is to coat an object with graphene. While this is not a method that would be used to create circuit pathways, it has some intriguing applications within the textile and garment industry. This could be used for items like fabric swatches that could be used to test dyes or other chemicals, or it could be used to create conductive fabrics for garments with high-voltage wiring. This could be especially useful for garments that are used in medical settings. Graphene could also be used for anti-counterfeiting as it has unique optical and physical properties. These properties allow it to be detected under a microscope, making it very difficult to counterfeit. Graphene could also be used as a way to make fabrics more stain-resistant. It could be applied as a coating to fabrics to create a protective barrier that prevents dirt and other stains from being absorbed. This could be particularly useful for fabrics like silk that are naturally more delicate. Graphene applied to fabrics could also be used as a way to make fabrics more durable and stronger.
The production of graphene ink is an exciting and promising new method of producing graphene. While it is not a new process, it does present unique benefits that could make it more suitable for specific industries. For example, certain production methods for graphene can be challenging to scale. In the case of graphene ink production, the process could be easily scaled up to meet demand. Another benefit of graphene ink production is that it is compatible with many of the existing digital textile printing methods, making it an easy transition for companies currently using other printing methods. Graphene ink has many exciting applications within the digital textile industry. It can be used in printed fabrics to create intelligent wearable technology and conductive pathways, and it can be used to coat objects like fabric swatches.
