| titleOfInvention | Cellulose nanocrystal and preparation method thereof based on redox system |
| abstract | The embodiment of the invention relates to a cellulose nanocrystal and a preparation method thereof based on a redox system. The preparation method comprises the following steps: swelling and crushing the cellulose raw material, and washing; dispersing the pretreated cellulose raw material in an aqueous solution containing an oxidizing agent and a reducing agent to carry out hydrolysis reaction; and carrying out post-treatment on the obtained hydrolysate to obtain the stably dispersed cellulose nanocrystal suspension. The preparation method uses the reducing agent and the oxidant as the auxiliary agent to participate in the hydrolysis reaction of the cellulose, and reduces the activation energy required by the oxidant to damage an amorphous region through the interaction between the oxidant and the reducing agent in the reaction system, so that the reaction is carried out under a mild condition and the reaction rate can be improved, therefore, the addition of the reducing agent improves the preparation efficiency to a certain extent, reduces the using amount of the oxidant, reduces the preparation energy consumption and saves the preparation cost. |
