Objective
- Development of transparent, electrically conductive coatings on glass using
redispersable, nanocrystalline ATO and ITO powder
Basic principle
- Preparation of ATO and ITO conducting powder using a precipitation process at the size
of primary particles
- Complete redispersion of the powders in water or ethanol by an appropriate modification
of the surface
- Deposition of single layer films by spin, dip or spray processes at room temperature
Results
- The coating solutions are longer than one year stable at room temperature, easy to
prepare, and recyclable
- Sheet resistances as low as:
ATO: 450 Wo (400 nm, 2 layers) and ITO: 100 Wo (reduced 400 nm single layer)

- High optical transmission:
Transmission and reflection spectra of ITO and ATO coatings
on glass
Applications
- LCD, LED, electroluminescent devices
- Touch screen panels
- Antistatic and antiglare coatings on glass and plastic
- ATO coatings:
- Gas sensors (CH4, CO, H2, C2H5OH, NOx)
- Abrasion and corrosion protection
- Electrical conductive ultrafiltration membrane material with narrow pore size,
adjustable from 2 to 20 nm
