Nanosecond Laser-Based High-Throughput Surface Nano-Structuring (nHSN) Process of Metal Alloys for Superhydrophobic and Anti-Reflective Surfaces

Detailed Technology Description: Dr. Ding and his lab havedeveloped a top-down nanosecond laser-based high-throughput surfacenano-structuring process. This allowsscale up of nano-structuring speed for a large surface area. This expedited process comprises two steps: ahigh energy nanosecond pulse laser scans, followed by a chemical treatment. Surface tests of wettability and reflectance demonstratedenhanced results for super-hydrophobic and anti-reflective properties. Microhardness on the processed surfaces werealso mechanically increased by roughly 20%.AdvantagesRapidhigh throughput surface treatmentTop-downapproach opposed to bottom-upEnhancedmicrohardness

*Abstract: Themetal fabrication market is expected to increase from $16.4 billion in 2015 to$21.4 billion by 2024. The use ofperiodic micro-/nano- scale fabrication provides opportunities for super-hydrophobicand anti-reflective surfaces. Thesebottom-up fabrication methods scan the material surface at a very fine spatialresolution to create the required hierarchical micro- and nano-scale structuresleading to an extremely low throughput.
