Switzerland has developed a metal wire conductive transparent fabric can greatly simplify the production of large-area flexible OLED, this new fabric-based wire due to the high conductivity, to ensure that the electrode in a long distance outside still show high conductivity, making it ITO An ideal alternative to transparent electrodes.

Researchers at Swiss Electronics and Micro Technology Center (CSEM) and precision fabric maker Sefar joined forces to design a novel fabric electrode that can be produced in a low-cost, roll-to-roll (R2R) process .

Researchers first weave wires and translucent polymer fibers with a diameter of about 40 μm into a precision net filled with an optically clear polymer and then thinly coat the solution-treated organic conductor (such as PEDOT: PSS) On the substrate, a flexible electrode free from indium tin oxide (ITO) was obtained, which was used to display a large area organic light emitting diode (OLED). Due to its high electrical conductivity, the metal base of such a fabric substrate ensures that the electrode exhibits high electrical conductivity over longer distances and that the same effect can be achieved even with a very thin, highly transparent conductive polymer layer.

According to Sefar's literature, the currently commercialized conductive fabric SECSAR TCS Planar exhibits about 90% light transmission over the entire visible and near infrared spectrum, sheet resistance of less than 0.1 Ω / sq, and even bending of up to 6 mm The bending radius hardly changes its conductivity. This makes it an ideal replacement for transparent electrodes, replacing expensive and fragile ITO layers in general electronic applications, from touch displays to solar cells and OLEDs.

This fabric can be further coated with a clear polymer that prevents it from penetrating liquids and gases while maintaining its conductivity and providing a protective layer of humidity and oxygen without significantly changing its transmission properties.
