Background: Cellulose being the most abundant polymer has been widely utilized in multiple
applications. Its impressive nanofibril arrangement has provoked its applications in numerous fields.
Recent trends have been shifted to produce composites of nanocellulose for numerous applications
among which the most important ones are its use in medical and environmental prospective. This review
has basically focused the development of nanocellulose composites and its applications in resolving environmental
Methods: We have reviewed large number of research and review articles from famous journals using a
focused review question. The quality of retrieved papers was assessed through standard tools. The contents
from reviewed articles were described in scientific way.
Results: We included 85 papers including research and review articles and patents in this review. 18 papers
introduced the theme of current review. More than 10 papers were used to describe the approaches
used for synthesizing cellullose nanocomposites. Composite synthesis strategies included the in situ addition,
ex situ penetration, solution mixing, and solvent casting etc. Around 60 manuscripts including 6
patents were used to demonstrate various applications of nanocellulose composites. Nanocellulose
based materials offer several applications in the development of antimicrobial filters, air and water filters,
filters for removal of heavy metals, pollutant sensors as well as applications in catalysis and energy
sectors. Such products are more efficient, robust, reliable, and environment-friendly.
Conclusion: This review gives a comprehensive picture of ongoing research and development on environmental
remediation by nanotechnology. We hope that the contents reviewed herein will catch the
reader’s interest and will provide interesting background to extend future research activities regarding
cellulose based materials.
