Embodiment 1
[0033] A preparation method of a cellulose nanofiber-based flexible transparent conductive film, the specific steps are as follows:
[0034] Step 1: Ultrasonic defoaming of the CNFs solution for 5 min to obtain a CNFs casting solution with a mass fraction of 0.10%;
[0035] Step 2: Pour the film casting liquid obtained in Step 1 into a flat-bottomed container, seal it and put it into an oven at 30°C, and obtain a CNFs film after the solvent is completely evaporated;
[0036] Step 3: Immerse the CNFs film obtained in Step 2 into AgNO with a temperature of 10 °C, a concentration of 0.1013 mol / L, and a pH of 7.00. 3 After taking out the solution, the film was washed with deionized water and air-dried to obtain CNFs / Ag + membrane;
[0037] Step 4. Adjust the pH value of the GO solution with a concentration of 1 mg / mL to the same as the above AgNO. 3 The pH value of the solution is the same, that is, the pH value is 7.00; then the CNFs / Ag obtained in step 3 + The membrane was i...
Embodiment 2
[0042] A preparation method of a cellulose nanofiber-based flexible transparent conductive film, the specific steps are as follows:
[0043] Step 1: Ultrasonic defoaming of the CNFs solution for 30 min to obtain a casting solution with a mass fraction of CNFs of 0.23%;
[0044]Step 2: Pour the film-casting liquid obtained in step 1 into a polypropylene watch glass, control the liquid level of the film-casting liquid in the watch glass to be 1.3 cm, seal it for a period of time, and put it into an oven at 40°C. After the solvent is completely evaporated, a CNFs film is obtained;
[0045] Step 3: Immerse the CNFs membrane obtained in Step 2 into CuCl at a temperature of 30 °C and a concentration of 0.0157 mol / L (pH value of 4.66). 2 After taking out the solution, rinse the film with deionized water and dry it with air;
[0046] Step 4. Adjust the pH value of the GO solution with a concentration of 8.7 mg / mL to the same as the above CuCl. 2 The pH value of the solution (4.66) ...
Embodiment 3
[0051] A preparation method of a cellulose nanofiber-based flexible transparent conductive film, the specific steps are as follows:
[0052] Step 1. Ultrasonic defoaming of the CNFs solution for 1 h to obtain a casting solution with a mass fraction of CNFs of 0.27%;
[0053] Step 2, pour the film casting liquid obtained in step 1 into a flat-bottomed container, evaporate naturally, and obtain a CNFs film after the solvent is completely evaporated;
[0054] Step 3: Immerse the CNFs membrane obtained in Step 2 into AlCl at a temperature of 70 °C and a concentration of 0.0371 mol / L (pH value of 4.02). 3 After taking out the solution, rinse the film with deionized water and dry it with air;
[0055] Step 4. Adjust the pH of the GO solution with a concentration of 3.5 mg / mL to the same value as the above AlCl. 3 The pH value of the solution (4.02) was the same, and then the CNFs / Al obtained in step 3 3+ The membrane was immersed in GO solution at a temperature of 70 °C, and afte...
