Environment-friendly regenerated cellulose based flexible memristive device

Limited nonrenewable resources on earth motivate people to use natural polymer materials in the development of environment-friendly devices for flexible electronics. In this work, a biocompatible and biodegradable organic memristor based on regenerated cellulose is prepared by a facile and green route. Here, cellulose, the key functional layer material, is used as not only the resistive switching layer but also a substrate to construct a flexible self-supporting memristor. Both volatile and nonvolatile resistive switching can be achieved by controlling the compliance current in the SET process. Moreover, this cellulose-based memristor performs competitive environmental and temperature stability compared with other organic memristors. This research provides a facile strategy for constructing an environment-friendly memristor based on natural polymer-based materials.
