Cost-effective micro- and nano-patterns on large-area flexible substrates are fabricated by means of roll-to-roll nanoimprint lithography.
The R2R pilot line allows a sustainable production of highly resolved conductive elements for organic electronics. It is possible to precisely create optical 2.5D structures for the light management in flexible films and to realize 3D-structured bionic surfaces (shark skin, lotus effect, gecko effect, structural colors). In addition, complex microfluidic elements on foil for bio-analytic lab-on-foil systems can be fabricated in a cost-effective way. Finally, a continuous production of optimized high-tech film surfaces for packaging, decoration, safety and labeling, which display improved optical, mechanical and chemical behavior due to their micro- and nano-structural properties is possible.
A wide range of applications for the produced large-area, low-cost, highly resolved, structured foils:
- Organic Electronics: conductive elements for thin conductors, nanoscale electrodes for organic transistors
- Light management: optical 2.5D structures on foils for coupling and out-coupling, light guiding
- Biomimetic structures: 3D-structured surfaces, imitating properties of biological structures
- Bio-analytics: cost-effective, microfluidic elements on foils for lab-on-foil systems
Packaging, decoration, safety, labeling: high-tech film surfaces exhibiting improved optical, mechanical and chemical behavior due to their micro- and nano-structural properties.
The aim of the rollerNIL project was to use roller-based nanoimprinting techniques to create complex optical structures over a large area in order to particularly replicate biomimetic structural colors. Associated nanoimprint masters and the imprint processes were developed, an inline process measurement system for roller-based fabrication was set up. The imprinting of undercut structures investigated in this project represents a significant development in NIL and shows its large-scale applicability for biomimetic structural colors.
MoMiFlu@Foil – Modular Microfluidic Systems on Plastic Foils for Bioanalytics
Flexible modular systems for individual, cost-efficient microfluidic based diagnostics. The Research Studio Austria (RSA) MoMiFlu@Foil develops roll-to-roll based, large area production methods for microfluidic systems on foil (labs-on-foil). These cost-efficient mini-labs enable highly efficient and complex analyses for single use diagnostics.
The project develops multifunctional – especially hydrophilic – UV imprint resins for a direct, cost-efficient and large-area production of microfluidic elements on flexible substrates. These labs-on-foil offer an interesting alternative to conventional injection molded and rigid plastic chips.
The Department focuses on the development of innovative structuring methods enabling large-area fabrication of flexible micro- and nanostructured foils or fully integrated components. The combination of printing (nanoimprint lithography) and structuring (ultra-short pulse laser techniques, electron beam lithography) methods permits the fabrication of innovative sensor systems. In addition, the group works on the development of circuits built of organic transistors and manufactured by innovative processes on flexible substrates, as there are foil, paper, and textile.
