Green Laser-Assisted Surface Structuring

Introduction

Biomimetic (BIOM), a spin-off of the Foundation for Research and Technology-Hellas (GR), was founded in 2020 to lead the exploitation of the results coming from a long R&D pathway on developing laser strategies for producing bionic surfaces (e.g. LiNaBioFluid and Biocombs4Nanofibers FET projects).

GLASS Technology

One of these investigations led to GLASS, a novel, cost-effective laser process capable of imprinting biomimetic antireflective (AR) nanostructures on glass. GLASS provides remarkable AR properties, using a single-step and environmentally friendly manufacturing process. This is in contrast to the most commonly used AR coating techniques in the industry, which involve the use of chemicals and multiple steps.

Commercial Applications

Considering the huge commercial applications that this unique laser strategy can have, such as:

1. Displays
2. Special optics
3. Digital cameras
4. Automotive
5. Telecommunication
6. Solar systems

With this project, BIOM will funnel efforts to address the major challenge of GLASS related to the mechanical durability of laser-treated glass.

Project Goals

The ultimate aim is the use of GLASS-produced AR glass for small-scale commercial applications, with an emphasis on consumer electronics displays and specialized optics markets.

Partnerships

For this purpose, BIOM is partnering with Corning Inc (CORN), currently the leading glass manufacturer for consumer electronics. Together, they will work on optimizing the GLASS process to meet the mechanical durability specifications of the two respective markets.

Co-Development

At the same time, BIOM will co-develop with LASEA, a recognized laser systems manufacturer, an automated GLASS laser system. These technical improvements will be validated by CORN, undertaking the role of customer, while BIOM, with the support of FORTH PRAXI NETWORK, a highly specialized company in technology.
