Two types of beta-chitin were prepared, with beta-chitin (a -\u003e b) subjected to acid treatment for decalcification and then base treatment for deproteinization, while beta-chitin (b -\u003e a) was treated in the opposite order. These beta-chitins were disintegrated into NFs using wet pulverization. The beta-chitin (b -\u003e a) NF dispersion has higher transmittance and viscosity than the beta-chitin (a -\u003e b) NF dispersion. For the first time, we succeeded in obtaining 3D images of the beta-chitin NF dispersion in water by using quick-freeze deep-etch replication with high-angle annular dark field scanning transmission electron microscopy. The beta-chitin (b -\u003e a) NF dispersion has a denser and more uniform 3D network structure than the beta-chitin (a -\u003e b) NF dispersion. Widths of the beta-chitin (a -\u003e b) and (b -\u003e a) NFs were approximately 8-25 and 3-10 nm, respectively. (C) 2016 Elsevier B.V.

内容記述 | We have investigated whether acidity can be used to control the physicochemical properties of chitin nanofibers (ChNFs). In this study, we define acidity as the molar ratio of dissociated protons from the acid to the amino groups in the raw chitin powder. The effect of acidity on the physicochemical properties of α- and β-ChNFs was compared. The transmittance and viscosity of the β-ChNFs drastically and continuously increased with increasing acidity, while those of the α-ChNFs were not affected by acidity. These differences are because of the higher ability for cationization based on the more flexible crystal structure of β-chitin than α-chitin. In addition, the effect of the acid species on the transmittance of β-ChNFs was investigated. The transmittance of β-ChNFs can be expressed by the acidity regardless of the acid species, such as hydrochloric acid, phosphoric acid, and acetic acid. These results indicate that the acidity defined in this work is an effective parameter to define and control the physicochemical properties of ChNFs. | |||||
