| FRAUNHOFER POLO ANNOUNCES ROLL-TO-ROLL PILOT PRODUCTION OF TRANSPARENT BARRIER FILMS FOR ENCAPSULATION OF FLEXIBLE ELECTRONICS AND SOLAR CELLS
Researchers from the Fraunhofer Polymer Surfaces Alliance POLO (Fraunhofer POLO) have developed highly effi cient barrier fi lms suitable for roll-to-roll production and that are now being produced on a pilot plant scale. The scientists have developed a sandwich structure of inorganic ceramic layers, which embed the patented hybrid coating ORMOCER®. The system has a very low water permeability of 2 x 10-4 g/m2/d, as measured in a calcium test at 38°C and 90% r.h.. Dr. Sabine Amberg-Schwab, spokesperson of the Fraunhofer POLO, points out: »The unique properties of the hybrid ORMOCER® layer boost the barrier properties of the inorganic barrier layers. This makes the barrier films suitable for demanding technical applications, such as for fl exible electronic devices.« The processing technology is a big step towards effi cient large-area production of flexible electronic devices such as fl exible solar cells, flexible OLEDs, and LCD-displays. The Fraunhofer POLO can reproducibly apply the barrier fi lm to various polymeric materials in a roll-to-roll process on a pilot plant scale. Dr. Nicolas Schiller, head of the »Flexible Products« department stresses: »The availability of barrier fi lms on a pilot scale is essential for developers of flexible electronic components. Moreover, the Fraunhofer POLO can customize films with further functionalities such as transparent conducting electrodes. We invite customers to govern the route for further developments in cooperation with Fraunhofer POLO.« Dr. Sabine Amberg-Schwab adds: »Our barrier material has superior performance, and the fi lms are fl exible and easy to use. We offer customers our expertise and assistance on fi lm application and handling operations. We also assist customers in the selection of adhesives and in the integration of our material into their production processes.« In a nutshell, the ultra-barrier fi lms are very versatile. Their properties can be adapted as required by the device manufacturer and various polymeric materials can act as suitable substrates. In addition, the barrier fi lm can be produced as needed and independently of the production of the device, and can then be laminated onto the substrate. About the Fraunhofer POLO The Fraunhofer Polymer Surfaces Alliance POLO brings together the individual expertise of seven Fraunhofer Institutes and develops innovative concepts for the functionalization of polymer surfaces. The Fraunhofer POLO offers support throughout the whole development phase, namely from the first fundamental experiments right through to scale-up and automation of the processes. The Fraunhofer POLO is the ideal partner for companies that manufacture and process polymers, and for users of polymers.
