CAMBRIDGE, UK PolyIC unveiled highly conductive transparent, high-resolution printed structures on film. Produced in a roll-to-roll production process, these conductive structures can be used as an alternative to ITO (Indium Tin Oxide) films in display, touch sensor or electric heating element applications.
The new PolyIC process offers various advantages over ITO alternatives, such as individual layouts to meet customer requirements, high transparency in a huge wavelength range, and customer-specific sheet resistance. The films can be produced in a roll-to-roll mass production process in high volume and are cost-effective in their applications.
With this newly developed technology, the company presents an attractive alternative for transparent conductive layers. Currently, for these applications, ITO films or thinly integrated metal wires are used. The conductive structures by PolyIC have a resolution of 15 micron.
They itself do not have to be transparent as the necessary translucence will be reached through the
high-resolution structure, that is, the conductive structures only occupy a fraction of the film (less than 10%). Through well-directed positioning of the process parameters it is possible to reach a conductivity of 0.4 to 1 Ω/m² for metal. The sheet resistance of the transparent film can be adjusted to typical values of ITO films.
