Transparent Conductive Films – the value of this market was estimated at approx. USD 5 billion in 2016. (based on IDTechEx report from 2016 and data from www.statista.com). The operation of displays, solar cells, touch screens and smartphones requires application of conductive layers (TCF) with the greatest possible neutrality to light (absorbed or emitted by the device) and at the same time with the highest possible conduction parameters. Currently, the most commonly used TCF layers are based on indium-tin oxide (ITO). Indium is a rare element whose supply on a global scale is mostly controlled by China (about 50% -60% of global production) and Korea (15% market share). Layers based on ITO are not flexible (a significant limitation for electronics manufacturers), they do not conduct enough electricity and have limited optical transparency. Due to the limitations of ITO, technology companies around the world are looking for new generation TCF layers technology as an alternative to ITO. Such technology has been developed and implemented by XTPL.
The heart of the XTPL technology is designed by company’s specialists innovative printing head. It operates on the basis of a unique algorithm & enables ultraprecise application of the ink with nanoparticles and formation of conductive lines. This revolutionary construction is subject to modifications that allow for dedicated application and optimization for a given application field. Basing on the customers’ requirements the company is providing versions adapted to obtain outstanding results.
Nanoinks manufactured by XTPL exhibit unique physicochemical properties that allow obtaining desired parameters of conductive lines. The majority of our inks are based on silver nanoparticles, we also use other nanomaterials and thanks to that we respond flexibly to the needs of our clients. The composition of XTPL’s nanoinks is each time precisely adjusted to specific requirements.
Nanoprinting system designed by XTPL makes it possible to precisely apply to the surface a special ink formulated for this purpose in the company’s laboratories. Under the influence of an external electric field, the nanoparticles in the ink create conductive lines according to the specified parameters. As such, the thickness of the individual lines (even below 100 nm), their length and the distance between them all vary depending on a specific application.
XTPL comprehensive solution for ultraprecise printing of nanomaterials allows for obtaining electrically conductive, optically, biologically and chemically active lines – width range: from below 100 nm to 15 μm. The feature size of printed structures is one of the key parameters in XTPL technology. What makes the XTPL technology unique is the possibility to create lines with a width-to-height aspect ratio close to 1 in a single pass of the printing head.
