Title: | Printing Smart Designs of Light Emitting Devices with Maintained Textile Properties | Authors: | VERBOVEN, Inge STRYCKERS, Jeroen Mecnika, Viktorija VANDEVENNE, Glen JOSE, Manoj DEFERME, Wim |
Issue Date: | 2018 | Source: | Materials (Basel), 11(2), p. 1-10 (Art N° 290) | Abstract: | To maintain typical textile properties, smart designs of light emitting devices are printed directly onto textile substrates. A first approach shows improved designs for alternating current powder electroluminescence (ACPEL) devices. A configuration with the following build-up, starting from the textile substrate, was applied using the screen printing technique: silver (10 µm)/barium titanate (10 µm)/zinc-oxide (10 µm) and poly(3,4-ethylenedioxythiophene)poly(styrenesulfonate) (10 µm). Textile properties such as flexibility, drapability and air permeability are preserved by implementing a pixel-like design of the printed layers. Another route is the application of organic light emitting devices (OLEDs) fabricated out of following layers, also starting from the textile substrate: polyurethane or acrylate (10–20 µm) as smoothing layer/silver (200 nm)/poly(3,4-ethylenedioxythiophene)poly(styrenesulfonate) (35 nm)/super yellow (80 nm)/calcium/aluminum (12/17 nm). Their very thin nm-range layer thickness, preserving the flexibility and drapability of the substrate, and their low working voltage, makes these devices the possible future in light-emitting wearables | Notes: | Deferme, W (reprint author), Hasselt Univ, Inst Mat Res IMO IMOMEC Engn Mat & Applicat, Wetenschapspk 1, B-3590 Diepenbeek, Belgium, Riga Tech Univ, Inst Design Technol, Kalku St 1, LV-1658 Riga, Latvia, Flanders Make Vzw, Oude Diestersebaan 133, B-3920 Lommel, Belgium.
