POLEOT (Printing of Light Emitters On Textile) is an ambitious project that contains technological and scientific challenges. It aims to develop a luminescence technology for producing innovative textiles with light‐emitting properties providing a wide range of new textile applications.
Electroluminescent (EL) and organic light‐emitting diodes (OLED) are light sources that are efficient, thin, lightweight and environment‐friendly. Applications based on glass substrates exist. Flexible lamps with metal or plastic foils as substrates are still under research. Prototypes of these materials have limited flexibility, because the transparent electrode is made of brittle indium tin oxide (ITO). The innovation of this project offers many advantages in comparison with the traditional EL/OLED lamps: large format lamps, mechanical resistance, high flexibility and roll‐to roll production.
At the heart of these light‐emitting textiles are new printable luminescent inks (OLED/EL). The project includes the development of printable light‐emitting inks for screen and digital ink jet techniques in full range that provide electroluminescent functionalities as well as conductive structures for a new generation of textiles in general and safety and signage in particular. Moreover, requested and adapted pre‐ and after‐treatment (carbon nanotube coating and barrier coatings against oxygen, respectively) techniques will be developed to optimize the light output
and lifetime during daily usage. The final product is a textile‐based EL/OLED that will be used to manufacture for example high‐visibility products for safety jackets or signalisation and large‐area architectural and automotive interior lighting.
