Preparation,Properties and Applications of Nanopaper Substrates for Flexible Electronics

Abstract

In recent years, "green" cellulose nanopaper made of nanocellulose has been considered as an alternative substrate for flexible electronics due to its unsurpassed quintessential physical and chemical properties, for example, biodegradability, light mass, mechanical flexibility, transparency, thermal stability, and compatible with well-established roll-to-roll manufacturing techniques. Nanopaper substrates for flexible electronics have gradually been a hotspot of research in academic and industrial community due to the increasing environmental concerns on electronic waste. The latest progresses in nanopaper substrates for flexible electronics were reviewed. The preparation, properties, and device applications of nanopaper substrates were elucidated in details, with specific emphasis on the current application status of nanopaper substrates in organic thin-film transistors, solar cells, and organic light emitting diodes. Moreover, several personal insights on the existing challenges and future research direction of nanopaper substrates were considered based on current advances.
