Outline of Final Research Achievements

Chitosan-HAp composite fiber was obtained by coagulation method. Sodium hydroxide treatment after the coagulation was effective for enhancement of not only HAp precipitation but also mechanical property. A chitosan mono-fiber crosslinked using a silane coupling reagent was also produced. The tensile strength of the fibers was improved by adding an appropriate amount of the silane reagent.
