%X Due to the worldĄŻs energy issues and dependency on
petroleum resources, focus has switched to finding new, sustainable raw
material sources for wood adhesives. Renewable biopolymers would gradually
replace petroleum and natural gas as the primary raw materials used in wood
adhesives. Chitosan is a biomass substance having a lot of reserves. Chitosan
is one of the most fascinating biopolymers in the adhesive sector because of
its potential qualities for adhesive applications, such as biodegradability,
biocompatibility, and non-toxicity. Chitosan and its derivatives have so
garnered considerable interest in a wide range of adhesive applications.
However, its adhesive strength is insufficient to glue wood under normal, humid
conditions. There has been a lot of study done on how to make chitosan-based
adhesives more cohesive and water resistant. In order to effectively use
chitosan-based wood glue in wood/wood composite adhesive that gives comparable
performance to synthetic adhesives, numerous new ways have been developed. It
has been modified by the addition of various cross-linkers, including aldehydes
like glyoxal glutaraldehyde etc</span><span style=\"font-family:&quot;\">.</span><span style=\"font-family:&quot;\">, epoxy compounds, blended with other polymers,
different acids and chitosan grafted onto vinyl acetate. In the production of
wood composites, chitosan can also scavenge formaldehyde. This review of
chitosan-based adhesives focuses on various cross-linkers for chitosan
modification in order to improve the properties of chitosan-based wood
adhesives.
