Russian scientists from AkKo Lab company (Moscow, Russia) have developed a nanoink based on titanium dioxide (TiO2). This type of nanoink was designed specifically for use in printed electronics. The distinctive feature of this nanoink is the fact that it consists of dissolved organic compounds so there are no particles which can be a reason of nozzle clogging in printer systems or coffee ring effect. Akko Lab Company has completed several experiments using a Fujifilm DMP printer, successfully printing a thin film of TiO2 nanoink on a variety of surfaces such as glass, ceramics, polyamide film, and so on. A unique property of this ink is its ability to control its own chemical reactivity, allowing the rheological properties of the ink to be manipulated during the printing process.
The TiO2-nanoink can be used for various industrial purposes, for example, gas sensors or solar cells manufacturing etc. Nowadays TiO2 and materials based on it are widely used in industrial production, and its properties are well studied. However, modern technologies for creating thin films of titanium dioxide don't generally apply to printing technologies. Nevertheless, printing technologies have many advantages in comparison with traditional production technologies. This particularly applies to the price of production, also form factor of end-product and scalability of production. Thus, expansion of kinds of printable materials, especially those which are already used in industry, is really important.
Nowadays AkKo Lab company (www.akkolab.ru ) produces and sells titanium dioxide, silver, gold and platinum nanoinks for printed electronics and other functional applications.
