Bio-based
materials open a new world of possibilities in every field due to its
independence from the petrochemical origin. Moreover, concerns on environmental
footprints and toxicity of synthetic adhesives made scientists investigate the utilization of biomaterials for wood
adhesives. In this perspective, nanocellulose as a sustainable and cheap
bio-nanomaterial provides a better alternative to conventional adhesivebased on formaldehyde-containing condensation resins. Property of nanocellulose to act as both binders
and as structural reinforcement in various adhesive systems adds to its
potential. Besidesby reducing the harmful emission of formaldehyde, it also can improvethe
mechanical properties and enhance performance of adhesives. This review paper
aims to point out the potential application of nanocellulosebased
wood adhesives compared to petroleum-based conventional systems beyond
renewability. New functionalities through structural modification in
nanocellulose could bring a replacement with the synthetic adhesive systems
which will play a significant role in future bio-economy.
