Nanocellulose-Graphene Hybrids: Advanced Functional Materials as Multifunctional Sensing Platform

Abstract

Highlights

The current status, ongoing challenges, and potential future outlooks of nanocellulose-graphene hybrids in multi-sensing applications are highlighted.

The fundamentals of synthetization, interfacial interactions, functionalization, and green fabrication techniques of nanocellulose-graphene hybrids are described.

The most advanced novel nanocellulose-graphene hybrids implementation as a multifunctional sensing platform is discussed.

Naturally derived nanocellulose with unique physiochemical properties and giant potentials as renewable smart nanomaterials opens up endless novel advanced functional materials for multi-sensing applications. However, integrating inorganic functional two-dimensional carbon materials such as graphene has realized hybrid organic–inorganic nanocomposite materials with precisely tailored properties and multi-sensing abilities. Altogether, the affinity, stability, dispersibility, modification, and functionalization are some of the key merits permitting their synergistic interfacial interactions, which exhibited highly advanced multifunctional hybrid nanocomposites with desirable properties. Moreover, the high performance of such hybrids could be achievable through green and straightforward approaches. In this context, the review covered the most advanced nanocellulose-graphene hybrids, focusing on their synthetization, functionalization, fabrication, and multi-sensing applications. These hybrid films exhibited great potentials as a multifunctional sensing platform for numerous mechanical, environmental, and human bio-signals detections, mimicking, and in-situ monitoring.
