“…[100] It was found that the ionic liquid 1-allyl-3-methylimidazolium bromide (AMIMBr) can swell the chitin to form gelatinous substance (ionic gels), and then ultrasonically treat it with methanol as solvent. [101][102][103][104][105][106] The chitin nanofibers with diameter of 20-60nm were prepared by regeneration technology. In recent years, the sodium hydroxide urea solution has been used as a good solvent for the dissolution of chitin.…”

Chitin is a kind of natural macromolecule material which was first discovered in mushrooms and was widely found in the shells of crustaceans and arthropods, the cell walls of fungi (yeast and mold) and algae, and the mollusks. The original chitin in nature usually has an antiparallel molecular chain alignment forming nanofibers connected by inter-and intramolecular hydrogen bonds. These microfibers consist of nanofibers about 2-5 nm in diameter, and about 300 nm long, embedded by protein matrices. Due to their unique dimensional, optical, mechanical, and other characteristics, the preparation of nano-chitin materials is an important subject. It is possible to extract nano-chitins from their sources with various methods, including acid hydrolysis, mechanical disintegration, TEMPO-mediated oxidation, electrospinning, and others. In this article, the latest progress in recent years in the preparation and applications of nano-chitin were reviewed. The morphology of the nano-chitins obtained from the above methods was presented. The advantages and disadvantages of each method were analyzed. An overview of applications of nano-chitins was discussed, including biomedicine, food applications, water treatment, green electronic materials, enzyme immobilization carriers, cotton textile materials, cosmetics, and others.
