It is known that the mechanical properties of the
composites are strongly related to the aspect ratio of
the filler particles. Based on this, the chitin whiskers,
having a wide range of aspect ratios, i.e. 10–120,
depending on types of sources, have been extensively studied as reinforcing nanofillers in recent
years[18–23]. Chitin or poly(b(1-4)-N-acetyl-D-glucosamine) is one of the most abundant polysaccharides found in nature. It can be found in the skeletal
materials of crustaceans, cuticles of insects, and cell
walls of various fungi. Chitin is known to be cytocompatible[24–26] and biodegradable[27]. In addition, chitin whiskers have been successfully
