Working With Us

At Haydale, we believe the properties of graphene and other nanomaterials can be realised. The key to this is our ability to selectively engineer the surface of the nanomaterials so that they can chemically interact through the functional groups, with the target matrix in a way that results in homogeneous dispersion. Material dispersion is the real key to realising the coveted properties that are so readily stated in the literature.

The ‘traditional’ methods of using chemical, mechanical and thermal treatments in the conversion of powdered graphite to Graphene Nanoplatelets (GNP) has scalability but often creates surface defects; surface engineering is also limited by the chemical groups within the chemicals and acids used. Conversely, epitaxial growth of graphene sheets (often by chemical vapour deposition, CVD) often creates the single sheets of graphene, but is limited by the substrate it is grown on. Removing the graphene from the substrate is tricky, and again, is often treated with harsh chemicals and thermal treatments. The resultant material is often not as desirable as before. To address these shortfalls, Haydale has pioneered a patented low temperature plasma scalable process for the functionalisation of graphenes and carbon nanotubes (CNTs). The process can functionalise with a range of chemicals (such as oxygen, ammonia and acid vapour) whilst the amount of chemicals can be tailored to specific customer needs. The Haydale HDPlas plasma process does not use wet chemistry nor does it damage the material being processed; rather it actually cleans up any impurities inherent in the raw material. Haydale plasma technology is a low energy user and most importantly, is environmentally friendly.

Through experience, we know that it is critical to select the right base material before seeking to surface engineer the nanomaterial, in order to deliver the desired properties. Haydale is not bound to using any particular graphene material or supplier we can select the base material most suited to your application needs; however, before becoming a preferred material of supply, we have stringent criteria on which we base our material selection on:

  • Identifying a supply source that offers consistent material
  • Ensuring that the material is of high quality
  • Determining the morphology of the nanomaterials
  • Confirming that our proposed solution is commercially viable for your application
