| description | The present invention discloses a method for preparing the nano-crystalline cellulose of a flexible screen matrix material. According to the preparation method, the bagasse unbleached pulp and the chitosan are adopted as raw materials. The bagasse unbleached pulp is dissolved and dispersed in water to prepare a suspension liquid. A mixed acid is then added in the suspension liquid. After the reaction process, a high-crystallinity suspension liquid is prepared. After the centrifugation process, solid matters are washed, and then are processed by a high-pressure ultrasonic homogenizer to obtain a nano-crystalline cellulose crystal suspension slurry. The potassium periodate is added into the suspension slurry for oxidation treatment to obtain a modified nano-crystalline cellulose suspension slurry. The chitosan material is treated with acetic acid at a low temperature to prepare a chitosan saturated solution. After the ultrasonic atomization freezing treatment, the nano-scale chitosan is prepared. The nano-scale |
