Embodiment 1
[0030] (1) Preparation of polydopamine-modified cellulose-based porous materials
[0031] Weighing 10 grams of the wood pulp cellulose nanowire suspension with a mass fraction of 1.3% was placed in a 50ml beaker, and at room temperature, 28.9mg of dopamine hydrochloride (dissolved in 1ml of water, slowly dropwise) was added under the effect of magnetic stirring Add), and adjust the pH to 8.5 with Tris-HCl buffer solution, keep the reaction at room temperature for 20h, add 130mg KH560 and continue to stir for 2h. Subsequently, the suspension was frozen with liquid nitrogen for 8 min and then freeze-dried on a freeze-drying agent for 48 h to obtain a polydopamine-modified cellulose-based porous material, which was baked at 110° C. for 30 min to increase the degree of crosslinking. Wherein, the porous material preparation method of the organosilane-modified cellulose-based porous material (ie, without PDA) was used as a blank control as described above.
