Perpetuus secures independent verification for the quality of its functionalised graphene materials

Quality test follows independent verification of Perpetuus’ high volume production capacity

Perpetuus Advanced Materials (“Perpetuus”), a British company at the forefront of advanced materials development, announces the successful results of a quality study on its functionalised graphenes by Cardiff University.

Graphenes, specifically functionalised by Perpetuus for use as nano enhancing fillers and enablers within polymers, were produced by Perpetuus under independently observed conditions and used in this test.

A full analysis and characterisation of the materials produced was undertaken by scientists at the Cardiff Catalysis Institute, School of Chemistry, Cardiff University, led by Dr. David Morgan. The analysis included Raman, XPS, XRD and Microscopy. Dr. Thierry Mathis of Swansea University supervised the SEM Microscopy for the quality study. The results of the study demonstrated that Perpetuus’ proprietary plasma production process delivered industrial scale quantities of highly crystalline, friable functionalised graphenes.

Many applications for graphene are limited by graphene typically being unable to exist unsupported over extended lengths and widths, instead stability is achieved through several – typically less than ten – layers. The study concluded the Perpetuus Plasma method of graphene production could generate stacks of typically under ten layer thicknesses, with high quality domains.

Perpetuus was pleased with the results and accordingly asked Dr. David Morgan to then test the same materials used in the study for applicability to a commercial environment by coordinating and supervising the production of conductive ink. The Directors were delighted that the resulting ink, with a resistivity of 5 ohm per square, was concluded in the test to be suitable for mass-market commercialisation. The study concluded: “This form of ink production offers a great improvement over existing methods.”

The graphene materials used in the Cardiff study were produced by Perpetuus as part of an independent quantity verification process. That procedure was undertaken by industrial process experts Scott Grant (attended by accountants Grant Thornton UK LLP as independent observers). The study concluded that Perpetuus had a theoretical production capacity of 140 tonnes per annum from a single reactor.

The Board of Perpetuus believes that the results from the independent quantity and quality studies of Perpetuus’ functionalised graphene materials show that:

  • Perpetuus has a production capacity of 140,000 kilos per annum; and importantly that
  • Perpetuus’ plasma production process can produce friable highly crystalline functionalised materials that are suitable for commercial use.

Perpetuus believes these two studies represent the first verifiable, comprehensive ‘full suite’ analysis of commercial quantity production of graphenes.

John Buckland, CEO of Perpetuus Advanced Materials, said:

“One of the greatest challenges the graphene industry faces today is how to produce high quality functionalised materials, on a large scale, at low cost, using reliable and robust technology.

By undertaking this independent study and making our graphenes available at £50 per kilogram, we hope to build confidence amongst potential producers of graphene enabled applications and products. I sincerely hope other graphene material producers invest in similar testing protocols, using the ‘full-suite’ characterisation and analysis developed by Cardiff and Swansea Universities.

“We are delighted that we have been able to independently verify the functionality of our conductive inks and pastes, which we believe begins to demonstrate the potential of 2D materials and allows potential customers real visibility of and the opportunity to gain confidence in our work.”
