- Detailed Technology Description
- A new, novelfabrication process for polymer nanopillars combining anodic aluminium oxide (AAO)templates and the Nanoimprint Lithography (NIL) process

- *Background
- Existingnanostructural coating approaches like spray coating [1], surface etching [2]and electrospinning [3] cannot accurately control coating parameters such asporosity, thickness and geometry. This results in non-uniform production ofnanostructure patterns with polymer materials. These existing manufacturingprocesses are expensive, need installation of specialized, sophisticatedequipment and require skilled personnel. A new technology, nanoimprint lithography(NIL) [4] has been shown to be a repeatable and low cost approach for obtainingnanostructural patterning. Compared to the traditional nanoscale fabricationmethods, the NIL approach is much easier to control for thickness, patterngeometry and location, resulting in asimple nanolithography process with low cost, high throughput and highresolution. There is currently no method for combining NIL technology with useof polymer templates. This would allow fabrication of large scale polymerpillars with high reproducibility, easy one step procedure of imprinting andchemical treatment and generate significant cost savings in the production.Figure1: Schematicsof the fabrication process for nanopillar polymer coating with nanoimprint: (a)spin coating with solid polymer film; (b) attach the AAO on the polymersurface; (c) package for nanoimprint process; (d) release the mold bydissolving the AAO in NaOH solution.
