Summary

Preparation of nanoscaled polymeric assemblies such as nanofibers and nanowhiskers is one of the most useful methods to practically utilize polymeric materials as observed in the case of cellulose. There are two major processes to produce the chitin nanofibers or nanowhiskers from the chitin source: one is disentanglement of chitin microfibrils and the other is regeneration from the chitin solution in appropriate solvents. As examples of the first technique, acid hydrolysis and 2,2,6,6‐tetramethylpiperidine‐1‐oxyl radical (TEMPO)‐mediated oxidation were previously reported. On the other hand, selected conditions for the regeneration of the chitin solutions simply gave chitin nanofibers/nanowhiskers. Electrospinning technique was also employed in the formation of chitin nanofibers from chitin solutions. This chapter deals with the above four methods as efficient processes for the preparation of chitin nanofibers/nanowhiskers. The applications of the resulting nanoscaled chitin assemblies to the practical composite materials are also discussed.
