Chitin-chitosan nanocomposite gels: reinforcement of chitosan hydrogels with rod-like chitin nanowhiskers
نویسندگان
چکیده
Nanocomposite gels containing chitosan as a network polymer and chitin nanowhiskers as reinforcing fillers were prepared by cross-linking with the blocked isocyanate hexamethylene-1,6-di-(aminocarboxysulfonate) (HDS). Young’s modulus and stress at break of the nanocomposite gels increased to maximum values of 169 and 135 kPa, respectively, with increase in whisker content up to 13.3%, whereas the degree of swelling decreased from 357 to 33.0.

Nanostructured biocomposite films of high toughness based on native chitin nanofibers and chitosan
Chitosan is widely used in films for packaging applications. Chitosan reinforcement by stiff particles or fibers is usually obtained at the expense of lowered ductility and toughness. Here, chitosan film reinforcement by a new type of native chitin nanofibers is reported. Films are prepared by casting from colloidal suspensions of chitin in dissolved chitosan. The nanocomposite films are chitin...

متن کاملUse of Polysaccharide Hydrogels in Drug Delivery and Tissue Engineering
Present review article aims to explain use of injectable hydrogels and microspheres derived from natural polysaccharides as drug delivery systems and cell scaffolds. Polysaccharides isolated from natural sources are proved much better than synthetic polymers for making single and composite hydrogels. This paper emphasizes recent developments occurred in use of amphiphilic polysaccharides for bi...

Chitin and Chitosan are polysaccharides found abundantly in nature. The presence of these polysaccharides is found largely in marine ecosystem next only to the plant source is noteworthy. Especially the production and consumption of crustaceans like crabs and prawns have increased in the recent years, thereby generating a large amount of solid shell waste. In the present study the crab, Scylla ...
متن کاملFunctional Characterization of Chitin and Chitosan
Chitin and its deacetylated derivative chitosan are natural polymers composed of randomly distributed -(1-4)linked D-glucosamine (deacetylated unit) and N-acetyl-D-glucosamine (acetylated unit). Chitin is insoluble in aqueous media while chitosan is soluble in acidic conditions due to the free protonable amino groups present in the D-glucosamine units. Due to their natural origin, both chitin a...
