The demand for thin film conductive materials has grown exponentially. The availability and applicability of traditional metallic and ceramic materials, however, is limited.
For example, existing technology used in electrochromic ceramic windows is slow to switch, and requires continuous power to maintain a dark state. Liquid crystal is not flexible, needs higher voltages (60V), and polarizes incoming light making it incompatible with LCD displays.
A unique polymerisation technique has been developed for thin films using conducting polymers.
One well-known example is poly (3,4-ethylene dioxythiophene), or PEDOT, an air-stable material which readily delivers conductivity over 2000 S/cm (i.e. 30Ω/□), with transparency typically in excess of 80%.
UniSA’s Generation 3 coating:
This technology is ideal for Augmented Reality (AR) headsets required for indoor and outdoor usage. The technology can be further developed to occlude background light, by pixilation, behind virtual images.
The intellectual property associated with this technology is patent protected.
UniSA Ventures is targeting manufacturers of AR headsets to use the technology and to develop greater speed, transparency, and pixilation.
The team of researchers at UniSA’s Future Industries Institute that have spear-headed this development, include:
