Large-Area Sub-Micron Structured Surfaces using Micro Injection Moulding Templates of Nanoporous Anodized Aluminum Oxide

The interactions between biological cells and nanometer-scale structured surfaces are very important issues in nanobiotechnology. Most current methods of fabricating such surfaces are costly and are not suitable for the production of a nanometer-scale structured surface that will be used merely as a disposable tool in cell biological studies. We developed and optimized an embossing method of polymers with nanoporous AAOs which is easy, cheap and fast in fabricating nanometer-scale structures on the surface of polymers. We think this method can be applied not only in cellular nanobiotechnogy but also in other areas of nanotechnogy.

A simple method for the fabrication of polymer master for antireflective surface is presented. In conventional fabrication methods for antireflective surface, coating method with low refractive index have usually been used. However, it is required to have a high cost and a long processing time for mass production. In this paper, antireflective surface was fabricated by using hot embossing process with porous anodized aluminum oxide. Through multi-AAO and etching processes, nano patterned master with high aspect ratio was fabricated at the large area. Size and aspect ratio of nano patterned master are about 175 ± 25 nm and 2 ~ 3, respectively. In order to replicate nano patterned master, hot embossing process was performed by varying the processing parameters such as temperature, pressure and embossing time etc. Finally, antireflective surface can be successfully obtained after etching process to remove selectively silicon layer of AAO master. Optical and rheological characteristics of antireflective surface were analyzed by using SEM, EDX and spectrometer inspection. Antireflective structure by replicating hot embossing process can be applied to various displays and automobile components.
