Abstract

In this study, we report on the production of succinylated β-chitin nanofibers (ChNF) via aqueous counter collision (ACC) method. Succinic anhydride (SA) mediated chemical modification is known as an effective nanofibrillation strategy for typical natural polysaccharides through the surface carboxylation, which has attracted attention due to its relatively mild characterisitics, such as non-toxicity. Using the combined physico-chemical treatment of SA and ACC, the succinylated β-chitin nanofiber (β-SChNF) was successfully prepared as a uniform hydrocolloidal suspension. The SEM and AFM analysis showed that the diameter of the SChNF ranged from 14 nm to 30 nm. The XRD and FT-IR analysis were used to confirm that the original crystal and chemical structure of chitin were maintained even after the physico-chemical nanofibrillation. We also fabricated a transparent film from the SChNF which showed a typical diameter-dependent optical transmittance; that is, the higher the number of ACC pass (i.e., smaller diameter of SChNF), the greater the optical transparency (80%). Our results show that SA chemical pre-treatment of β-chitin can boost successful nanofibrillation.
