Electrochromic Displays Screen Printed on Transparent Nanocellulose‐Based Substrates

Manufacturing of electronic devices via printing techniques is often considered to be an environmentally friendly approach, partially due the efficient utilization materials. Traditionally, printed components (e.g., sensors, transistors, and displays) are relying on flexible substrates based plastic materials; this especially true in display applications where, most times, a transparent carrier required order enable presentation content. However, plastic‐based ruled out end user scenarios striving toward sustainability. Paper ordinary cellulose fibers can potentially replace substrates, but opaqueness limits range where they used. Herein, electrochromic displays that manufactured, screen printing, directly state‐of‐the‐art fully nanocellulose presented. Several different nanocellulose‐based either nanofibrillated or nanocrystalline cellulose, manufactured evaluated as for manufacturing displays, optical electrical switching performances resulting reported compared. The do not require use metals and/or conductive oxides, thereby providing sustainable all‐printed technology.
