Amphiphilic, ultralight, and multifunctional graphene/nanofibrillated cellulose aerogel achieved by cation-induced gelation and chemical reduction

Abstract

Nanofibrillated cellulose (NFC) was incorporated to reduced graphene oxide (rGO) for fabrication of multifunctional amphiphilic aerogels. The as-prepared amphiphilic aerogel showed excellent recoverability, superior absorption capacity for both organic solvents and water, and an electrical conductivity sensitive to compressive strain making it highly potential to be used as a pressure-responsive sensor.
