Screen printable functionalised graphene ink

Graphene is a carbon based material which is inherently inert and which does not like to mix with, or bond to, other materials. Its excellent properties can only be fully realised when this fundamental hurdle is overcome, and it can be properly dispersed and covalently bonded into matrices such as inks via a process known as functionalisation*.

To enable scientists and printers to develop their own processes and products, Goodfellow is offering screen printable ink containing plasma functionalised Graphene Nanoplatelets from Haydale.

Typical uses include: Light flexible displays, plastic electronics, printed circuit boards, thin film photovoltaics, e-paper, sensors, electrodes and OLEDs.

How is this ink different?

  • Made with HDPlas® functionalised Graphene Nanoplatelets (GNPs)
  • Electrically conductive
  • Flexible on appropriate substrate
  • Metal free, 100% organic (non-tarnishing)
  • Curable at low temperatures
  • Can be applied to a variety of surfaces
  • High print resolution
  • Environmentally friendly
  • Low mass
  • Customisable

Handling and Storage

These inks are intended for research and industrial use by trained personnel. It is important for workers to avoid overexposure to chemicals contained in these products. Always consult the Material Safety Data Sheet (MSDS) and product labels before using the products. Keep product container closed when not in use to prevent solvent evaporation and spilling hazard.
