GLASS · Green Laser-Assisted Surface Structuring

Biomimetic (BIOM), spin-off the Foundation for Research and Technology-Hellas (GR), was founded in 2020 to lead the exploitation ofthe results coming from a long R&D pathway on developing laser strategies for producing bionic surfaces (e.g. LiNaBioFluid andBiocombs4Nanofibers FET projects). One of these investigations led to GLASS, a novel, cost-effective laser process, capable to imprintbiomimetic antireflective (AR) nanostructures on glass. GLASS provides remarkable AR properties, using a single-step andenvironmentally friendly manufacturing process, contrary to the most used AR coating techniques in industry that involve the use ofchemicals and multiple steps. Considering the huge commercial applications that this unique laser strategy can have (e.g. displays,special optics, digital cameras, automotive, telecommunication, solar systems), with this project BIOM will funnel efforts to addressthe major challenge of GLASS related to the mechanical durability of laser treated glass. Ultimate aim is the use of GLASS-producedAR glass for small-scale commercial applications, placing emphasis on consumer electronics displays and specialized optics markets.For this purpose, BIOM is partnering with Corning Inc (CORN), currently the leading glass manufacturer for consumer electronics, towork together on optimizing the GLASS process to meet the mechanical durability specifications of the two respective markets, whileat the same time will co-develop with LASEA, a recognized laser systems manufacturer, an automated GLASS laser system. Thesetechnical improvements will be validated by CORN undertaking the role of customer, while BIOM with the support of FORTH PRAXINETWORK, a highly specialized company in technology
