Graphene production

HydroGraph Clean Power has announced that its patented Hyperion System, designed for scaled-up production of high-purity graphene, achieved a key technology milestone to produce commercial scale quantities graphene. 

The Hyperion System will produce fractal graphene to serve various markets including lubricants, energy storage, resins, specialty chemicals, coatings and other markets. The validation process reportedly confirmed the capex cost per metric ton of graphene produced will be one of the lowest in the industry. The system can produce over 10 metric tons per year using readily available commodity acetylene and oxygen.

Gerdau Graphene, a nanotechnology company focused on the production, development, and commercialization of graphene-enhanced materials for industrial applications, has announced that it has landed the first sales of its graphene-enhanced Poly-G PE-07GM polyethylene masterbatch. The additive is suitable for the production of films, profiles, and sheets formed through the extrusion processes.

The new thermoplastic products created using Poly-G PE-07GM are said to be stronger and offer greater overall performance while costing less to manufacture and producing significantly less waste across the value chain. Poly-G PE-07GM was piloted in a series of industrial applications within Gerdau’s factories before
commercialization, including as a film for construction nail packaging. Gerdau found that by using the new, 25% thinner graphene-enhanced plastic film, far fewer nails perforated the packaging. As a result, Gerdau reported a 39% reduction in the volume of discarded damaged packaging and a 7% increase in
film productivity.

Professor Lars Borchardt’s team at Ruhr University Bochum, Germany, has succeeded in carrying out light-driven chemical reactions in the solid-state without resorting heavily to solvents. The team stated that this provides a sustainable alternative to established synthesis methods.

Light is considered the ideal driving force of chemical reactions as it’s cheap, available in abundance and produces no waste. This is why light-driven, i.e. photochemical reactions are highly attractive for the production of chemical compounds. However, they are usually carried out in huge amounts of solvents that are often toxic and generate hazardous waste in enormous quantities. Solid-state photochemical reactions without solvents could present an alternative. However, they have hardly been feasible so far, as they could only be mixed insufficiently and so it was possible to scale them up to relevant quantities.

Versarien has announced the launch of Umbro's ProTraining Elite range, including garments incorporating the Company's Graphene-Wear technology.

Versarien has been working with Umbro since 2018 and these are the first products to be launched in Europe incorporating the Company's technology.  Umbro's new ProTraining Elite long-sleeve running tops, baselayers and running tights have Versarien's Graphene-Wear ink formula printed on the inside.  The Graphene-Wear formula features novel properties that will allow wearers to experience enhanced thermal transmittance, increased moisture management, with improved drying rate, without compromising air or water vapor permeability.  In particular, these three garments will benefit significantly from applying Graphene-Wear as they are being worn in circumstances where maintaining core body temperature is more desirable and difficult to achieve.  The garments also have Versarien's Graphene-Wear trademark applied.

It was reported that industrial production of graphene recently commenced in Kerala, India, with the manufacturing beginning at Carborundum Universal Limited under the Murugappa Group. 

Carborundum Universal has designed a special project, Grapheno, as part of the production of the nanomaterial. It had set up a lab and a plant spread over 12,000 sq ft at Kakkanad as part of the initiative. The company has reportedly signed agreements with Manchester University, IIT Chennai, the Cochin University of Science and Technology (Cusat) and others for industrial research.

Liquid metal catalysts have recently been attracting attention for synthesizing high-quality 2D materials facilitated via the catalysts’ perfectly smooth surface. However, the microscopic catalytic processes occurring at the surface are still largely unclear because liquid metals escape the accessibility of traditional experimental and computational surface science approaches. 

An EU-funded collaboration of researchers that included teams from Fritz Haber Institute of the Max Planck Society, The European Synchrotron- ESRF, Technical University of Munich (TUM), Aarhus University,  Leiden University and Université Grenoble Alpes used novel in situ and in silico techniques to achieve an atomic-level characterization of the graphene adsorption height above liquid Cu, reaching quantitative agreement within 0.1 Å between experiment and theory.

Malaysia-based graphite and single-layer graphene producer, Graphjet Technology (GTI), recently signed a Letter of Offer to build its RM400 million (over USD$90 million) production facility in the Phase 3 of Malaysia-China Kuantan Industrial Park.

Graphjet's patented technology aims to transform palm kernel shell, a waste from palm kernel production, into single-layer graphene, at a significantly lower cost than the current production of single-layer graphene. The production plant is expected to produce 10,000 tonnes of graphite and 60 tonnes of single-layer graphene annually. 

UK-based PlanarTECH offers R&D and production-scale equipment and services for all classes of emerging 2D materials and carbon-based materials such as CNTs and CVD diamonds. In 2020 planarTECH launched a successful equity crowdfunding campaign as it aims to expand its business and enter new markets such as industrial CVD graphene production systems and material production.

We have recently talked to the company's CEO, J. Patrick Frantz, who gives us the latest business and technology updates from PlanarTECH.

Q: Can you update us on your latest business activities, with a focus on graphene?

We had a very difficult time during the pandemic, as many companies did. From July 2020 through June 2021 we shipped just one CVD system. However, we started to see a resumption of customer activity towards the end of 2021 as labs reopened and people around the world got back to work. For 2022, we’re seeing a complete recovery and are on our way to the best year we’ve ever had in terms of sales.

On 1 July 2020, Versarien announced that the UK Government, via Innovate UK, had granted a £5 million loan to the Company, for a project named G-SCALE, an acronym for Graphene, Seat, Concrete, Arch, Leisure, Elastomer. The award was to facilitate the production of sufficient quantities of graphene to enable commercialization of graphene-enhanced products in these five priority application areas.

Recently, Versarien has provided a summary of G-SCALE progress for each of the relevant segments. 

Researchers from India's SRM Institute of Science and Technology have reported on a natural, environmentally friendly and sustainable surfactant for exfoliating graphene in water.

Aqueous graphene dispersions hold potential for many applications such as printed and paper electronics and polymer composites, but the water’s surface energy tends to be too high to stabilize them. However, surfactants provide adequate repulsive potential against restacking of exfoliated nanosheets in colloidal dispersions to overcome the van der Waal’s attractive forces. The major problem with reported and commercial surfactant resources is their inability to produce micrometer-sized graphene with few defects at high yield with using a minimal amount of economical and sustainable surfactants.
