Microstructure formation via roll-to-roll UV embossing using a flexible mould made from a laminated polymer–copper film

Roll-to-roll large format UV embossing processes aim to revolutionize the manufacturing of functional films, with the ability to process a large area at one time, resulting in high throughput and cost reduction. In this paper, we present the experimental results obtained during the process developme...
