TLDR
Chitin is the most abundant natural amino polysaccharide and is estimated to be produced annually almost as much as cellulose, and recent progress in chitin chemistry is quite noteworthy as mentioned in this paper.Abstract:
Chitin is the most abundant natural amino polysaccharide and is estimated to be produced annually almost as much as cellulose. It has become of great interest not only as an underutilized resource, but also as a new functional material of high potential in various fields, and recent progress in chitin chemistry is quite noteworthy. The purpose of this review is to take a closer look at chitin and chitosan applications. Based on current research and existing products, some new and futuristic approaches in this fascinating area are thoroughly discussed.read more

Chitin and chitosan polymers: Chemistry, solubility and fiber formation
TL;DR: In this paper, a review discusses the various attempts reported on solving this problem from the point of view of the chemistry and the structure of these polymers highlighting the drawbacks and advantages of each method and proposes that based on considerations of structure-property relations, it is possible to obtain chitin fibers with improved strength by making use of their nanostructures and/or mesophase properties of chitins.

Structural changes of pH‐sensitive chitosan/polyether hydrogels in different pH solution
TL;DR: In this article, the swelling of crosslinked chitosan/polyether interpenetrating polymer network (semi-IPN) hydrogel is found to be dependent on the protonation of amino groups and the dissociation of hydrogen bonding within the network, which is related to solution pH.
