Peelable porous nanosheet fabricated by roll-to-roll coating and nanoimprinting technique

Large-area, continuous roll-to-roll nanoimprinting with PFPE composite molds.

Successful implementation of a high-speed roll-to-roll nanoimprinting technique for continuous manufacturing of electronic devices has been hindered due to lack of simple substrate preparation steps, as well as lack of durable and long lasting molds that can faithfully replicate nanofeatures with high fidelity over hundreds of imprinting cycles. In this work, we demonstrate large-area high-spee...

Dye-less color filter fabricated by roll-to-roll imprinting for liquid crystal display applications.

A diffractive grating is promising for color separation to effectively replace conventional absorptive dye color filter in liquid crystal displays. In this paper, we demonstrated a color separation module consisting of an aspheric-lenticular lens array and a blazed grating to substitute for the dye color filter. Each component was designed to match the recent fabrication ability of our roll-to-...

Bioinspired superhydrophobic surfaces, fabricated through simple and scalable roll-to-roll processing

A simple, scalable, non-lithographic, technique for fabricating durable superhydrophobic (SH) surfaces, based on the fingering instabilities associated with non-Newtonian flow and shear tearing, has been developed. The high viscosity of the nanotube/elastomer paste has been exploited for the fabrication. The fabricated SH surfaces had the appearance of bristled shark skin and were robust with r...

Roll-to-roll large-format slot die coating of photosensitive resin for UV embossing

Roll-to-roll large-format coating and UV embossing processes aim to revolutionise the manufacturing of functional films, with the ability to process a largearea at one time, resulting in high throughput and cost reduction. In this article, we present the experimental results obtained during the process development for roll-toroll large-format coating and UV embossing. We have investigated key a...
