Summary

This chapter describes isolation and characterization of natural chitin nanofibers (CNFs) from different sources and the composite preparations from these NFs. CNFs are isolated from different sources such as crab shells, prawn shells, shrimp shells, and edible mushrooms. CNFs were isolated from the cell walls of mushrooms by a number of chemical treatments to remove glucans, minerals, and proteins associated with mushrooms followed by grinding treatment in acidic conditions. A reinforced acetylated CNF composite can have promising applications as it is an optically functional composite. Reinforcement of CNFs by resins or reinforced resins by CNFs improve physical properties such as Young's modulus, fracture stress and strain, coefficient of thermal expansion (CTE) and flexibility, transparency, and hygroscopicity. Favorably modified properties show that neat CNFs or blended fibers have vast applications in the future as advanced biologically benign nanocomposites.
