Embodiment 1
[0041] First prepare the bacterial cellulose porous material cross-linked by the silane coupling agent. The specific preparation process is as follows: take bacterial cellulose (Hainan Coco Food Co., Ltd.) with a length of 10 cm and a width of 5 cm and immerse it in 200 mL of NaOH solution with a concentration of 0.25 mol / L After heating at 80°C for 4 h, the bacterial cellulose was taken out and washed with deionized water until neutral. Afterwards, the bacterial cellulose was immersed in 200 mL of deionized water, heated at 80° C. for 4 h, and then the bacterial cellulose was taken out and washed 4 times with deionized water. The above-mentioned pretreatment process on the bacterial cellulose was repeated 7 times, and then the treated bacterial cellulose was shredded and stirred at a speed of 10000 r / min for 1 hour by a homogenizer to obtain a bacterial cellulose suspension. Finally, take 10 g of bacterial cellulose suspension, add 2 g of KH550, stir at room temperature for 2...

[0046] First prepare the bacterial cellulose porous material cross-linked by the silane coupling agent. The specific preparation process is as follows: take bacterial cellulose (Hainan Coco Food Co., Ltd.) with a length of 10 cm and a width of 5 cm and immerse it in 200 mL of NaOH solution with a concentration of 0.5 mol / L After heating at 100°C for 6 h, the bacterial cellulose was taken out and washed with deionized water until neutral. Afterwards, the bacterial cellulose was immersed in 200 mL of deionized water, heated at 100° C. for 6 h, and then the bacterial cellulose was taken out and washed 4 times with deionized water. The above-mentioned pretreatment process on the bacterial cellulose was repeated 10 times, and then the treated bacterial cellulose was shredded and stirred at a speed of 20000 r / min for 2 hours by a homogenizer to obtain a bacterial cellulose suspension. Finally, take 10g of bacterial cellulose suspension, add 4g of KH560, stir at room temperature for ...

[0051] First prepare the bacterial cellulose porous material cross-linked by the silane coupling agent. The specific preparation process is as follows: take bacterial cellulose (Hainan Coco Food Co., Ltd.) with a length of 10 cm and a width of 5 cm and immerse it in 200 mL of NaOH solution with a concentration of 0.4 mol / L After heating at 90°C for 5 h, the bacterial cellulose was taken out and washed with deionized water until neutral. Afterwards, the bacterial cellulose was immersed in 200 mL of deionized water, heated at 90° C. for 5 h, and then the bacterial cellulose was taken out and washed 4 times with deionized water. The above-mentioned pretreatment process on the bacterial cellulose was repeated 8 times, and then the treated bacterial cellulose was shredded and stirred at a speed of 15000 r / min for 2 hours by a homogenizer to obtain a bacterial cellulose suspension. Finally, take 10 g of bacterial cellulose suspension, add 3 g of A-151, stir at room temperature for 2...
