[0041] The nickel-graphene fiber layer is prepared by the following method:
[0042] Slowly add 2g flake graphite to 50g mass fraction of 98%H 2 SO 4 And 3g mass fraction is 85%H 3 PO 4 In the mixture, the temperature of the system is controlled at 5°C, and 3g KMnO is slowly added under stirring 4 and 3g K 2 Cr 2 o 7 The mixture was reacted for 3 hours, then heated up to 30°C and continued to react for 2h, then slowly added 100g of deionized water, raised to 90°C for 1h, then cooled to 30°C and added dropwise 20g of hydrogen peroxide, reacted for 50min, ultrasonically dispersed for 1h to obtain graphene oxide nanosheet dispersion.
[0043] Take 50 g of the graphene oxide nanosheet dispersion liquid and heat it to 60 °C in the reactor, and add 6 g of Ni 2 SO 4 ·6H 2 O, heat preservation reaction 50min, then cool down to room temperature, slowly add Na under stirring 2 CO 3 , adjust the pH value of the solution to 2.0, add 2g penetrant and 2g citric acid, ultrasonic...
