One‐Step Production of Organized Surface Architectures on Polymeric Materials by Direct Laser Interference Patterning

In this communication, we report a novel method for the advanced design of architectures in polymers in a single step process. Direct Laser Interference Patterning (DLIP) permits the fabrication of repetitive 1D and 2D patterns and microstructures by direct irradiation of the sample surface with coherent beams of light. In addition, the most important advantage of this method is that no additional process steps (i.e. etching, development of photoresist) are required.
