titleOfInvention | A kind of dialdehyde nanocellulose three-dimensional flexible material and its preparation method and application |
abstract | The invention discloses a dialdehyde nanocellulose three-dimensional material and a preparation method and application thereof. The preparation method of the dialdehyde nanocellulose three-dimensional material of the present invention includes the following steps: (1) High oxidation of the matrix: mixing the nanocellulose dispersion with an oxidizing agent, adjusting the pH to an acidic value, mixing uniformly, and heating the reaction in the dark to obtain the initial hydrogel; (2) freeze-drying of the matrix: the initial hydrogel is washed with water, frozen in liquid nitrogen, freeze-dried in vacuum, and washed with water again to obtain a three-dimensional material of dialdehyde nanocellulose. The material of the invention has a flexible network structure, has extremely high modification value, can still maintain its shape in a wet environment, has good compression resilience and water resistance; the surface also has abundant hydroxyl and aldehyde groups, which can be used as The active sites were further functionalized, and the obtained dialdehyde nanocellulose solid amine adsorbent could adsorb acid gases. |
