Abstract

The present invention provides a method for producing chitin nanofibers, which includes the steps of deproteinizing a material derived from a chitin-containing organism by an alkali treatment, deashing a deproteinized integument by an acid treatment, optionally treating the deashed integument under acidic conditions, and then subjecting to a fiber-loosening treatment. The present invention also provides chitin nanofibers obtained by the method, and a composite material and a coating composition each containing the same. The present invention provides a method for producing chitosan nanofibers, which includes, in addition to the above steps, a deacetylation step and chitosan nanofibers obtained by the method, and a composite material and a coating composition each containing the same.
