微纳米结构在快速、低成本和大面积生产方面表现出日益增长的商业兴趣。激光方法具有巨大的潜力,易于制造表面结构的柔性聚合物箔,如聚酰亚胺(PI)。本文对KrF准分子激光用于聚合物箔结构的两种不同概念进行了测试和比较:激光诱导烧蚀和激光诱导激波结构。这些聚合物的直接正面激光照射允许制造不同的表面结构。例如:低激光通量处理的PI产生纳米级锥体结构,其中锥体密度可以由激光参数控制。这使得激光制造微观QR码和高分辨率灰调图像成为可能。此外,激光处理的前面的聚合物箔允许背面结构由于激光诱导的冲击波。用光学显微镜、扫描电子显微镜(SEM)和白光干涉测量仪(WLI)分析了合成的表面结构。
Micro- and nanostructures exhibit a growing commercial interest where a fast, cost-effective, and large-area production is attainable. Laser methods have a great potential for the easy fabrication of surface structures into flexible polymer foils like polyimide (PI). In this study two different concepts for the structuring of polymer foils using a KrF excimer laser were tested and compared: the laser-induced ablation and the laser-induced shock wave structuring. The direct front side laser irradiation of these polymers allows the fabrication of different surface structures. For example: The low laser fluence treatment of PI results in nano-sized cone structures where the cone density can be controlled by the laser parameters. This allows inter alia the laser fabrication of microscopic QR code and high-resolution grey-tone images. Furthermore, the laser treatment of the front side of the polymer foil allows the rear side structuring due to a laserinduced shock wave. The resultant surface structures were analysed by optical and scanning electron microscopy (SEM) as well as white light interferometry (WLI).
