Promethean Particles Collaborates To Develop Innovative Storage Solution For Historical Artefacts

Promethean Particles is collaborating with European partners to develop innovative packaging and storage solutions in support of the preservation and conservation of vital historical artefacts and documents.

Utilising its ground-breaking continuous flow production process, Promethean is developing Metal Organic Frameworks (MOFs). These are highly porous materials that are able to selectively adsorb the acetic acid which is responsible for the degradation of cellulose acetate that many 20th century audio and visual ‘memories’ are made from. Today, many artefacts are stored in archives or boxes which do not offer adequate protection.

Research scientist at Promethean Particles, Charles Toft, said: “When acetic acid is produced, it accelerates the degradation of the artefact even further and, once started, this damage is irreversible. Thousands of photographs, films, posters and slides are lost forever because of this damaging process.

“We are working with organisations from across Europe, as part of the NEMOSINE project, to develop innovative packaging solutions that will overcome the challenges that storing documents and artefacts over long periods of time presents.”

The NEMOSINE project has received funding from the European Union’s Horizon 2020 research and innovation programme and is made up of 16 partner organisations.

Promethean is working closely with another project partner that produces MOFs with the required functional properties via a lab-scale batch process. Promethean then adapts the batch method onto its continuous flow reactor systems to manufacture MOFs with the same, or similar, functional properties and facilitate upscaling.

Initial performance testing has generated positive results and Promethean is now focused on scaling up the manufacturing process to produce larger quantities, validate the material, and ensure the solution will be commercially viable.

Toft added: “Promethean operates a market-disrupting continuous-flow production process meaning the MOFs are reproducible on a large scale, without affecting performance and quality. By achieving economies of scale in production, we can support the commercial viability of the project’s results. Importantly for Promethean, the MOFs being developed can also be utilised in other applications such as chemical filtration and separation within a wide range of industries, so the commercial opportunities opening up as a result of this work are really quite exciting!”

In addition to the research by Promethean, other NEMOSINE partners are developing sensors to detect oxygen and humidity levels, as well as anti-fungal agents, to prevent microbial build-up during archived storage. The final outcomes of the project would therefore deliver a revolution in protecting historical items.
