Graphene Inks: introduction and market status
Versarien updates on recent progress
Versarien has shared updates on its progress across several key sectors and markets, reporting a growing pipeline of opportunities, rising from £1.6 million (over USD$2 million) in October 2023 to £4.7 million currently (over USD$6,100,000), with £1.6 million (over USD$2 million) in commercial opportunities and £3.1 million (over USD$4 million) in grants. The Company said it continued to focus on developing advanced materials, especially graphene, through manufacturing-light operations and technology licensing.
In the construction sector, the company said it had placed orders for equipment to enhance its in-house construction testing capabilities following a July fundraising. The equipment would support the development of graphene-based products, such as Cementene. Versarien said it had also signed its first significant 3D construction printing (3DCP) contract with Building For Humanity CIC for a project in Accrington, UK. The Company anticipated on-site activities to begin in 2025.
AMD announces breakthrough that could open new opportunities replacing metals in printed electronics
Researchers from Advanced Material Development (AMD) and the University of Sussex have announced what they refer to as "a major enhancement" in their carbon nanomaterial-based inks, reaching conductivity levels of 3,000,000 Sm-¹, approaching the performance of incumbent metal-based solutions.
With years of experience with graphitic inks, that previously achieved industry-best conductivity of 500,000 Sm-¹ (several times more conductive than other non-metal inks) - the latest breakthrough seems to significantly raise the bar.
Haydale Graphene Industries and Staircraft report progress on graphene-based underfloor heating trials
Specialist structural flooring manufacturers Staircraft have been testing the use of Haydale's graphene-based functional ink for application on their innovative chipboard flooring system. Significant investment has reportedly been made to get the new flooring system to adopt a heating solution that is cost effective and easy to install.
In a recent trial, Staircraft has reported very encouraging results and is now focused on continuing to collect definitive data before introducing the concept to their customer base.
Researchers develop improved graphene micro supercapacitors for wearables
Researchers from China University of Petroleum (East China), Henan Agricultural University and Chinese Academy of Sciences have developed an additive-free 3D printing process to construct graphene micro-supercapacitors (MSCs) with unprecedented electrochemical properties and seamless integrability. The team states that this achievement overcomes existing manufacturing limitations and brings closer the on-chip MSC arrays essential for the next generation of wearables.
Wearable devices require ever-smaller on-board energy solutions that can deliver bursts of power while remaining unobtrusive. Rigid coin batteries restrict device flexibility and ergonomics. Leading microscale alternatives include micro-supercapacitors (MSCs), which store and discharge energy rapidly owing to highly porous electrode materials interfacing with electrolytes. Supercapacitors’ quick charge ability and resilience to repeated charging cycles make them appealing to supplement batteries. However, difficulties producing intricately designed MSC devices that also offer high performance have confined MSCs to the lab. Conventional manufacturing techniques often lack suitable precision, flexibility, and scalability.
Versarien's turnaround strategy to benefit from Gnanomat's new funding
Versarien has reported that its Spanish business has secured funding for a new project, in a boost to the group’s turnaround strategy. The Company said its majority-owned subsidiary, Gnanomat, has been awarded a grant of around €415,000 (around USD$445,660) by a government body.
Gnanomat will use the money to help develop and commercialize a new line of conductive inks based on Versarien's nanomaterials, for use in the production of electronic goods.
Haydale announces new contract with Cadent for graphene ink-based low-power radiator heaters
Haydale has announced its next collaboration with Cadent, to develop graphene ink-based low-power radiator heaters. The £350,000 three-stage project will run for 12-months and is aiming to develop a tested and validated market-ready product as a cost-effective alternative for Cadent's customers when their gas supply is interrupted.
Following continued success on the low-power, battery operated water heating development, the aim for the latest project is to incorporate the same graphene-ink based technology into different designs to deliver bespoke solutions for a wide range of customer requirements.
Researchers develop "e-skin" from graphene and seaweed microcapsules
Researchers at Queen Mary University, University of Sussex and University of Brighton have integrated graphene into seaweed to create nanocomposite microcapsules for highly tunable and sustainable epidermal electronics. When assembled into networks, the tiny capsules can record muscular, breathing, pulse, and blood pressure measurements in real-time with ultrahigh precision.
The team explained that much of the current research on nanocomposite-based sensors is related to non-sustainable materials. This means that these devices contribute to plastic waste when they are no longer in use. The new study shows that it is possible to combine molecular gastronomy concepts with biodegradable materials to create such devices that are not only environmentally friendly, but also have the potential to outperform the non-sustainable ones.
Haydale awarded SMART funding to bring graphene products to market
Haydale has announced that it has been awarded SMART Flexible Innovation Support ("SMART FIS") from The Welsh Government to accelerate the development of its graphene underfloor heating product and range of biomedical sensor inks.
As part of a new innovation strategy for Wales, aimed at supporting Welsh industry by increased investment in research, development, and innovation, SMART FIS will provide Haydale with funding totaling £182,843 over a two-year period. Part of this funding will enable Haydale to accelerate the development of its prototype graphene underfloor heating ("UFH") towards a market-ready CE product that can be tested in a home environment. It will support continued engagement with partners such as City Energy Network Ltd and Plumbase.
LayerOne and SINTEF collaborate on graphene-based conductive inks project
LayerOne (formerly Abalonyx) and SINTEF (a Norway-based research institute) have secured funding from The Norwegian Research Council for the development of innovative, scalable and sustainable conductive inks based on reduced graphene oxide (rGO). The rGO-based inks promise improved electrical conductivity and stability surpassing traditional carbon-based inks and offering a less toxic and more cost-effective alternative to metal-based inks.
The research project is a result of LayerOne’s recent breakthrough in developing a new grade of rGO with an electrical conductivity two orders of magnitude greater than standard rGO grades. In the project, LayerOne will supply the advanced rGO materials while SINTEF will leverage and build on its experience from recently concluded projects on printed electronics to develop the new conductive inks.
Researchers develop a sprayable graphene biosensing platform for rapid and low-cost chemical sensing
Scientists from Imperial College London and Catania University & CNR-IMM have developed a novel graphene ink that can be used to detect a variety of chemical substances when layered on top of commercially available printed circuit boards (PCBs) as a thin film.
In their recent paper, the team demonstrated a novel and versatile sensing platform, based on electrolyte-gated graphene field-effect transistors, for easy, low-cost and scalable production of chemical sensor test strips. The Lab-on-PCB platform is enabled by low-boiling, low-surface-tension sprayable graphene ink deposited on a substrate manufactured using a commercial printed circuit board process.
