Embodiment 1
[0031] S1, preparation of nanocellulose
[0032] Add 1g of microcrystalline cellulose and 100ml of distilled water into the ultrasonic cell breaking cup for ultrasonic treatment. The ultrasonic power is 1500W, and the ultrasonic time is 0.5h. After standing still, the upper layer suspension is concentrated by rotary evaporation and freeze-dried to obtain powdered nanocellulose. (NCC);
[0033] S2, preparation of dialdehyde-based nanocellulose
[0034] Take 1g of the above-mentioned nanocellulose powder, dissolve it in 100ml distilled water to form a 1% (m / v) NCC suspension, add 1g of sodium periodate, stir magnetically under dark conditions, then undergo high-speed centrifugation, ultrasonic dispersion, and finally let it stand Take the upper suspension, concentrate it by rotary evaporation, and freeze-dry to obtain powdered nanocellulose (DNCC) with a dialdehyde-based structure;
[0035] S3, preparation of silver-loaded nanocellulose
[0036] Take 0.1 g of the above-mentio...
