Chitin Nanofibers, Preparations and Applications
نویسندگان
چکیده
Chitin nanofibers (CNFs) are mainly extracted from crab and prawn shells [1, 2] and recetly found in small amount in edible species of mushrooms [3]. CNFs are composed of chitin compound. Chitin in powder form is obtained from fish industry wastes which is otherwise thrown as industrial waste. Since CNFs are biodegradable having typical width 10-20 nm and large surface-to-mass ratio thus they are being prepared, studied, and applied more recently world wide along with rapidly growing field nanotechnology dealing with the better proper‐ ties of materials when their sizes are smaller in the range 1-100 nm. Fibrilated chitin in the form of highly viscous gel suspension in water has found scope in pharmaceuticals [4], chiral separation [5], fillers in silsesquioxane [6]. When blended with inorganic metals to prepare advanced hybrid organic-inorganic composites they can have applications in electronics, electrical, optical devices and much needed solar energy production.

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 کاملPreparation of Chitin Nanofibers from Mushrooms
Chitin nanofibers were isolated from the cell walls of five different types of mushrooms by the removal of glucans, minerals, and proteins, followed by a simple grinding treatment under acidic conditions. The Chitin nanofibers thus obtained have a uniform structure and a long fiber length. The width of the nanofibers depended on the type of mushrooms and varied in the range 20 to 28 nm. The Chi...
