R2R NANOIMPRINT LITHOGRAPHY

Roll-to-Roll plant at JOANNEUM RESEARCH Materials

Large-area micro- and nanostructuring

Our roll-to-roll nanoimprint lithography (roll-to-roll NIL, R2R NIL) facilitates continuous and therefore cost-effective production of micro and nanopatterns on large-area flexible substrates targeting electronic, optoelectronic, photovoltaic and sensoric applications, film processing and packaging as well as pharmaceuticals and biosciences.

R2R NIL is a revolutionary step forward, based on discontinuous embossing processes (batch nanoimprint lithography techniques) introduced in the 1990s.

Our R2R activities are one of the core topics within the <link internal link in current>Micro and Nanostructuring group (Director: Barbara Stadlober).

3D-Nano-Structures in Roll-to-Roll

The R2R pilot line allows us:

  • to sustainably produce highly resolved conductive elements for <link internal-link internal link in current>organic electronics (thinconductors, nanoscale electrodes for organic transistors), 
  • to precisely create optical 2.5D structures for the light management in flexible films (coupling and outcoupling, light guiding) for applications in <link internal-link internal link in current>photonics,
  • to realize 3D-structured bionic surfaces and <link internal-link internal link in current>complex nanopatterns on a large scale, which allow the artificial imitation of biological characteristics (shark skin, lotus effectgecko effect, structural colors), 
  • to produce complex microfluidic elements on foil for <link internal-link internal link in current>bioanalytic lab-on-foil systems in a cost-effective way, and
  • to continuously produce optimized high-tech film surfaces for packaging, decoration, safety and labeling, which display improved optical, mechanical and chemical behavior due to their micro and nanostructural properties.
