| Abstract: |
| The cellulose in garlic skin was extracted by sodium hydroxide（NaOH）/urea mixture at low temperature，and then nano cellulose was precipitated by adding potassium permanganate （KMnO４）solution with a mass fraction of 0. 05. The nano cellulose was characterized by Fourier transform infrared spectroscopy，scanning electron microscopy and X-ray diffraction spectroscopy. The results showed that the crystallinity of nano cellulose extracted by this method was relatively high，reaching 73. 8%.Combined with the thermogravimetric analysis of nano cellulose，it could be inferred that the nano cellulose treated with KMnO４ solution had excellent mechanical properties. |
