Abstract:
(EN) A process for producing chitin nanofibers is provided which includes the steps of: subjecting a material derived from a chitin-containing organism to an alkali treatment to deproteinize the material; subjecting the deproteinized integument to an acid treatment to deash the integument; optionally treating the deashed integument under acidic conditions; and then fibrillating the integument. Also provided are: chitin nanofibers obtained by the process; and a composite material and a coating composition both containing the chitin nanofibers. Furthermore provided are: a process for producing chitosan nanofibers which includes a deacetylation step besides those steps; chitosan nanofibers obtained by the process; and a composite material and a coating composition both containing the chitosan nanofibers.
(FR) L'invention porte sur un procédé pour la production de nanofibres de chitine, lequel comprend les étapes consistant à : soumettre un matériau issu d'un organisme contenant de la chitine à un traitement alcalin pour déprotéiniser la matière; soumettre le tégument déprotéinisé à un traitement acide pour le décendrage du tégument; éventuellement traiter le tégument décendré dans des conditions acides; puis fibriller le tégument. L'invention porte également sur : des nanofibres de chitine obtenues par le procédé; et un matériau composite et une composition de revêtement contenant tous deux les nanofibres de chitine. L'invention porte en outre sur : un procédé pour la production de nanofibres de chitosane qui comprend une étape de désacétylation en plus de ces étapes; des nanofibres de chitosane obtenues par le procédé; et un matériau composite et une composition de revêtement contenant tous deux les nanofibres de chitosane.
(JA)  本発明は、キチン含有生物由来の材料をアルカリ処理にて脱蛋白し、脱蛋白された外皮を酸処理にて脱灰し、所望により脱灰された外皮を酸性条件で処理し、次いで、解繊処理する工程を含む、キチンナノファイバーの製造方法を提供する。本発明は、該方法により得られるキチンナノファイバー、ならびにそれを含む複合材料および塗料組成物も提供する。上記工程に加えて脱アセチル化工程を含むキトサンナノファイバーの製造方法および、該方法により得られるキトサンナノファイバー、ならびにそれを含む複合材料および塗料組成物を提供する。
