“…A promising architecture for the incorporation of biodegradable constituents are organic light-emitting devices that show efficient planar electroluminescence and work on flexible substrates. Applications include smart packaging, which demands economic and ecological components for monitoring or advertising13, and custom fit disposable medical devices that can be used for phototherapy14. The more common organic light-emitting diode (OLED)15 requires functional multi-layer stacks and air-sensitive electron injection materials to reach high performances.…”

In this work, we demonstrate the use of the biodegradable polymer polycaprolactone (PCL) as the ion solvating polymer in solution-processed light-emitting electrochemical cells (LEC). We show that the inclusion of PCL in the active layer yields higher ionic conductivities and thus contributes to a rapid formation of the dynamic p-i-n junction and reduction of operating voltages. PCL shows no phase separation with the emitter polymer and reduces film roughness. The devices show light-emission at voltages as low as 3.2 V and lifetimes on the order of 30 h operating above 150 cd m−2 with turn-on times <20 s and current and luminous efficacies of 3.2 Cd A−1 and 1.5 lm W−1 respectively.

“…There is much ongoing research to develop roll-to-roll embossing and increase its range of applications Guo 2008, 2009;Kololuoma et al 2004;Krebs 2009;Mäkelä et al 2007;Nagato et al 2010;Velten et al 2008;Yeo et al 2010). By fulfilling the aims of lower cost and higher throughput, roll-to-roll embossing is targeted to be a commercially viable method for fabricating of micro and nano scale structures.…”

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

2011

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 areas of the processes with the aim of improving them in the long term through the understanding of the key factors associated with them and their effects on the processes. The areas investigated are the UV-curable liquid resin, the roll-to-roll film substrate, the coating process and quality, and the UV embossing process and quality. The emphasis is placed on the investigation of the coating process and quality. The results show that the rollto-roll coating and embossing processes are capable of producing micro-scale structures and functional devices over a large area at one time. They are complex processes with many factors playing important roles.

“…Thus, it presents itself as a perfect complementary approach to the traditional methods for microelectronics fabrication. The additive character of printed electronics, combined with its compatibility with on-foil fabrication at large area and high-throughput by means of roll-to-roll [1,2], renders it the best candidate for a number of new applications demanding large area, low-cost per surface area, light weight and mechanical flexibility, such as artificial skin [3][4][5] or smart packaging [6]. As a consequent, printed sensors based on electronic components are becoming increasingly popular.…”
