About Haydale

Haydale has developed a patent-pending proprietary scalable plasma process to
functionalise graphene and other nanomaterials. This enabling technology can
provide Haydale with a rapid and highly cost-efficient method of supplying
tailored solutions to enhance applications for both raw material suppliers and
product manufacturers.

Functionalisation is carried out through a low-pressure plasma process that
treats both mined, organic fine powder and other synthetically produced
nanomaterial powders, producing high-quality few layered graphenes and graphene
nanoplatelets. The process can functionalise with a range of chemical groups,
with the level of functionalisation tailored to the customer's needs. Good
dispersion improves the properties and performance of the host material and
ensures the final product performs as specified.

The Haydale plasma process does not use wet chemistry, nor does it damage the
material being processed; rather, it can clean up any impurities inherent in
the raw material. The technology is a low energy user and most importantly
environmentally friendly. The Haydale method is an enabling technology,
allowing the Company to work with a raw material producer who seeks to add
value to the base product and tailor the outputs to meet the target
applications of the end user.

Haydale, based in South Wales and housed in a purpose-built facility for
processing and handling nanomaterials, is facilitating the application of
graphenes and other nanomaterials in fields such as inks, sensors, energy
storage, photovoltaics, composites, paints and coatings.
