Printed electronics is normally categorized into three families:

  • Conductors: constitute the biggest volume of a printed circuit
  • Semi-conductors: allow you to build logic in the printed circuit (transistors – switches, diodes etc.)
  • Dielectrics: are there to boost the electric content to allow lower voltage applications and for certain components like capacitors

Copper

Applications:

  • Functional pigment for printed inks:
    Printed conductive tracks, ultrafine screen features, flexible substrates
  • Printed components: fully printed PCBs, antennas etc.

Key selling points:

  • Nano-copper (approximately 100 nm)
  • Conductive metal
  • Cost-effective alternative to silver
  • Contains only Cu and an antioxidant
  • Cost-effective process due to low CAPEX and OPEX costs
  • Scale-up of continuous production achieved (multi-kg batches)
  • Non-oxidised material, standard 60% wt Cu available in range of solvents (even customers’ specific blends,
  • Final formulated ink (made with our nano-copper dispersion) approved for inkjet, screenprinting, flexography and gravure.

Silver

Applications:

  • Functional pigment for printed inks:
    Printed conductive tracks, ultrafine screen features, flexible substrates
  • Printed components: fully printed PCBs, antennas etc.

Key selling points:

  • Nano-silver (approximately 50 nm)
  • Highly conductive metal
  • Used for higher demanding applications
  • Water based composition, no environmental impact or personnal risks
  • Scale-up of continuous production achieved

Barium Titanate

Applications:

  • Dielectric material, high dielectric constant
  • Capacitors, dielectric for printed components (i.e. Thin Film
    Transistors, diodes), piezo of electric material

Key selling points:

  • Small primary particle size (less than 20 nm)
  • One of the highest dielectric constant materials
  • Water based pigment
  • Suitable for screenprinting

Indium doped Zinc oxide

Applications:

  • Used as a semi-conductor i.e. large area displays, LCD, OLEDs

Key selling points:

  • Inkjetable dispersion which removes the need for etching
  • Used for TFT
  • Final formulated ink (made with our dispersion) approved for inkjet, screenprinting and gravure.

Nickel

Applications:

  • Used as a conductor or an electrode material (i.e. solar cells)
  • Used as batteries (Nickel-Iron batteries)
  • Strong magnetic properties, could be used in several applications

Key selling points:

  • Low oxidation rate
  • Strong magnetic properties
  • Straight forward material as no overcoat is required while depositing the material.
