Summary
Chitosan, a naturally derived polysaccharide, has attracted considerable attention due to its excellent biocompatibility, biodegradability, and functional versatility. This Special Issue aims to showcase recent advances in the design, fabrication, and application of chitosan-based materials. We invite contributions focusing on two-dimensional (2D) structures, such as films and coatings, as well as three-dimensional (3D) architectures, including scaffolds, hydrogels, and composites. Studies addressing the chemical modification of chitosan, its incorporation into polymeric matrices, and its impact on mechanical, biological, and physicochemical properties are highly encouraged. Applications across biomedicine, food packaging, cosmetics, and environmental fields are particularly welcome. Both original research articles and comprehensive reviews are invited to provide a broad perspective on the current trends and future challenges in this rapidly evolving area.
Suggested themes for submissions include:
− Design and fabrication of chitosan-based 2D and 3D materials (e.g., films, membranes, scaffolds, hydrogels, sponges, composites).
− Chemical modification and functionalization of chitosan to enhance physicochemical, mechanical, and biological properties.
− Applications of chitosan-containing materials in biomedicine, food packaging, cosmetics, and environmental protection.
This issue will serve as an essential resource for researchers and industry practitioners interested in developing and applying innovative polymeric-based materials.
