Preparation of nanochitin using deep eutectic solvents

iScience, Год журнала: 2024, Номер 27(3), С. 109312 - 109312

Опубликована: Фев. 23, 2024

SummaryChitin is an abundant and renewable non-wood biopolymer. Nanochitin formed by the assembly of chitin molecules, which has advantages large tensile strength, high specific surface area, biodegradability, so it been widely used. However, traditional methods preparing nanochitin have many drawbacks. As new generation green solvents, deep eutectic solvents (DESs) successfully applied in fields dissolution, extraction, preparation. In this review, relevant knowledge chitin, nanochitin, DESs was first introduced. Then, application status summarized, with a focus on preparation using DESs. conclusion, review provided comprehensive analysis published literature proposed insights development trends field DESs, aiming to provide guidance assistance for future researchers.Graphical abstract

Chemical Modifications of Chitin and Chitosan Fibers and Filaments: A Review

Macromolecular Chemistry and Physics, Год журнала: 2025, Номер unknown

Опубликована: Март 3, 2025

Abstract This review examines the chemical modifications of chitin and chitosan fibers filaments, emphasizing their potential for diverse applications. It discusses a variety modifications, including amidoximation, acetylation, partial deacetylation, N‐ maleation, naphthaloylation, halamination, grafting, oxidation, phosphorylation, sulfation, acylation, Schiff base formation, quaternization, nucleophilic substitution, hydroxyethylation, ureidation transformations. These significantly enhance properties chitosan, improving solubility, dispersibility, hydrophobicity, environmental stability, mechanical strength, antimicrobial activity, hemostatic capabilities, among other characteristics. By strategically tailoring these biopolymers through novel materials with enhanced functionalities can be synthesized. advanced are crucial developing functional products broad applications across various fields, spanning from biomedicine to sustainable composites.
