Functional coatings are an ideal way to endow products with new properties by using just a minimum of extra material. Fraunhofer ISC develops customized coatings based on inorganic materials and hybrid polymers suited for roll-to-roll processing. These coatings are non-flammable, environmentally friendly and suitable for flexible applications.
The standard coating employing ORMOCERs may serve as a protection layer for microelectronics and simultaneously works as passivation and encapsulation agent without degrading the performance. In battery systems, ORMOCERs can be used as polymer electrolytes for flexible battery cells or as a protecting shell for electrode materials to enhance the performance of thin solid-state cells.
Improved ultra-barrier ORMOCER coatings provide insulation for flexible organic electronic devices such as light emitting diodes, solar cells or OLED displays to protect them from water and oxygen in order to guarantee an adequately long lifetime. The ultra-barrier layers are flexible, transparent and adaptable to specific customer requirements. Biodegradable coatings with novel bioORMOCER®s developed by Fraunhofer ISC for food and pharmaceutical packaging are the next step. These bioORMOCERs can upgrade conventional films in their barrier properties against water vapor, oxygen, flavors, plasticizers and additionally show antimicrobial activity.
Electrochromic coatings made from conductive polymers are integrated in film laminates for intelligent light shading systems in windows of aircraft cabins, cars, or buildings.
Fraunhofer ISC performs material syntheses from lab to pilot scale employing modular roll-to-roll processing equipment from Coatema Coating Machinery GmbH. The institute offers to run test coatings under clean room conditions and develops formulations according to the individual production requirements of partners from the industry. Interested companies are invited to visit the Coatema Coating Machinery GmbH booth at nano tech 2016 to obtain information about equipment and R&D for coating, printing and laminating in roll-to-roll and sheet-to-sheet configurations.
In addition, Fraunhofer ISC provides customized syntheses of nanoparticles for the preparation of paints, printing inks or plastics formulations.
Using modern 3D printing techniques, the Fraunhofer-Center HTL – part of the Fraunhofer ISC – develops and fabricates customer-specific parts, prototypes and small-scale series using metals and metal-ceramic composites as well as porous and dense ceramics.
