Conductive polymers are organic, recyclable and inexpensive, and can now rival the performance of metallic coatings. UniSA has developed a unique patented method of producing thin film coatings of the conductive polymer PEDOT.
This coating process has very broad application, ranging from new sensors to new display technologies and “smart” windows. UniSA has already secured a license with one industry partner and the next step is to build a pilot manufacturing plant to realise these opportunities.
The demand for thin film conductive materials has grown exponentially. The availability of traditional metallic materials, however, is decreasing and their price has increased significantly. A single material – Indium Tin Oxide (ITO) – currently dominates the transparent conductor industry.
Considerable research has been invested into developing flexible and more sustainable materials.
Our research team has developed a unique polymerisation technique for poly (3,4-ethylene dioxythiophene), or PEDOT, which incorporates a complementary coating process and delivers conductivity up to 3400 S/cm (i.e. 24Ω/□), with transparency typically in excess of 80%.
Commencing over five years ago, the team has continually improved the source PEDOT and the coating process, to arrive at our current Generation 3 coating.
Conductivity and transparency along with flexibility are the key factors for a broad range of industry applications. Our PEDOT coating process provides world-leading performance, with very high conductivity while remaining transparent.
We are now looking for opportunities to build out our manufacturing capability to meet specific product applications.
The platform technology is now ready for the commercial arena and incorporated into a wide range of products including:
The intellectual property associated with this groundbreaking development has been protected under a platform patent application.
UniSA Ventures is targeting the completion of a PEDOT pilot manufacturing plant, and its operation over a 12-month period. The Pilot Plant will be dedicated to proving out the manufacturing process to service the products/markets identified. We are seeking partners to provide industry input and funding into this development.
