Abstract

Acetylation is a promising method for hydrophobic modification of cellulose-based materials. However, the current methods to prepare acetylated cellulose nanofibers (ACNFs) are often time- and energy-consuming. In this work, acetylated cellulose nanofibers (ACNFs) were fabricated by integrating acetylation and mechanical nano-defibrillation. The morphology and structure of the obtained ACNFs are characterized by means of atomic force microscope (AFM), Fourier transform infrared spectroscopy (FT-IR), solid state 13C NMR spectra, X-ray diffraction (XRD), etc. The yield of ACNFs can be as high as 96.5% for acetylated cellulose with low degree of substitution (such as DS of 0.15). The diameter and length of ACNFs are in range of 3–7 nm and 200–1100 nm, respectively. Due to their amphiphilic property (the water contact angle is 62.5°), ACNFs can be used as stabilizers for Pickering emulsion. The features of the emulsion in this study can be controlled by varying the DS and concentration of ACNFs.
