German materials firm Heraeus has announced a strategic partnership with Toagosei to increase the market penetration of its Clevios invisible patterning technique for transparent conductive PEDOT:PSS.
Under the agreement Toagosei will be granted a licence to sell the Clevios technology.
Alternative to ITO, Clevios Etch can be used to lay down conductive polymers to form touch panels and sensors. Hereaus has used the equipment to create thin layers of its conductive polymers with a resistance of less than 100 ohms per square meter.
The most immediate application for Clevios now is as a replacement to indium tin oxide (ITO) in backplanes for consumer screen technology. ITO for touchscreens is laid down using industrial sputtering techniques; these are more expensive than the inkjet printing, spin coating and slit coating mechanisms available with Clevios.
Indium is also an expensive metal with a limited global supply and ITO is inflexible so substituting away from it will allow increased flexibility for plastic screens, as well as cutting costs.
Partners
By forming an alliance with Toagosei, Heraeus will gain access to its expertise in deploying advanced materials and manufacturing techniques into product applications. This will include the experience the Japanese firm has gained evolving its own patterning production technique for transparent conductive materials - Clearimaju. Clevios and Clearimaju will now be sold together by Toagosei.

Stephan Kirchmeyer, the manager of Heraeus's displays and semiconductors division, says: 'The partnership with Toagosei is an enabling technology, generating exciting new business opportunities and options for the touch display industry. With this patterning technology, displays can be more economic, of higher optical quality and even can be curved or flexible.'
