Green and cost-effective synthesis of flexible, highly conductive cellulose nanofiber/reduced graphene oxide composite film with deep eutectic solvent

Developing efficient strategy for nanomaterials dispersion is the key for promoting the utilization of cellulose-based composite in energy storage devices. In this study, an instant synthesis method for cellulose nanofiber (CNF)/reduced graphene oxide (rGO) composite film with a deep eutectic solvent (DES) based on choline chloride and urea as a media is developed. This DES shows favorable abilities of recyclability, materials dispersion, and...
