Nanocellulose for green electronics

Abstract

Biodegradable, transparent and flexible transistors electronics have been a great interest for many industries in the past few decades. In particular, biodegradable and renewable nanocellulose-based substrates are attractive due to their highly remarkable properties in terms of physical, mechanical, optical and even biological. Previous research shown that nanocellulose-based materials can form the substrates and dielectrics of various devices such as organic field-effect transistors (OFETs), solar cells, batteries, and supercapacitors. To the best of our knowledge, there are no reports on utilizing nanocellulose-based materials for organic electrochemical transistors (OECTs). As comparing to OFETs, OECTs possess the advantages of high transconductance (mS) and low operating voltage (< 1V). In addition, the concepts of ion injections from an electrolyte to regulate the conductivity of organic semiconductor channel, make them particularly superior for a wide range of applications in bioelectronics and implantable medical detection. For this study and experimental report, nanocellulose paper is being evaluated and analysed to understand more about the advantages of integrating nanocellulose as a substrate for organic electrochemical transistors.
