Embodiment 1
[0021] (1), first in deionized water, add the block surfactant P123, place it in an ultrasonic stirrer for 30 minutes, and the solution is uniform and uniform, supporting a colorless transparent liquid, wherein the concentration of P123 is 5% ( v / v); then add reduced vitamin C (Vc), the concentration is 5% (wt%), and Vc needs to be prepared and used now;
[0022] (2), adding the silicon carbide nano-whiskers through surface cleaning into the solution obtained in step 1, ultrasonically dispersed for 20 minutes; the content of silicon carbide whiskers in the resulting mixture is 50%; the cleaning process is to Silicon nano whiskers were soaked in hydrochloric acid for 4 hours, and then washed with deionized water until the pH was 7;
[0023] (3), the arginine of concentration 10% is added in the mixture that step 2 obtains; The amount of the added arginine makes the pH value of solution 10, then adds a certain amount of zinc chloride and sulfur in mixed solution successively So...
Embodiment 2
[0026] (1), first in deionized water, add the block surfactant P123, place it in an ultrasonic stirrer for 10 minutes of ultrasound, the solution is even and uniform, supporting a colorless transparent liquid, wherein the concentration of P123 is 5% ( v / v); then add reduced vitamin C (Vc), the concentration is 2% (wt%), and Vc needs to be prepared and used now;
[0027] (2), adding the silicon carbide nano-whiskers through surface cleaning into the solution obtained in step 1, ultrasonically dispersed for 20 minutes; the content of silicon carbide whiskers in the resulting mixture is 30%; the cleaning process is to Silicon nano whiskers were soaked in hydrochloric acid for 2 hours, and then washed with deionized water until the pH was 7;
[0028] (3), the arginine of concentration 10% is added in the mixture that step 2 obtains; The amount of the added arginine makes the pH value of solution be 8, subsequently adds a certain amount of zinc chloride and sulfur in mixed solution...
Embodiment 3
[0031] (1), first in deionized water, add the block surfactant P123, place it in an ultrasonic stirrer and ultrasonically for 15 minutes, the solution is even and uniform, supporting a colorless transparent liquid, wherein the concentration of P123 is 8% ( v / v); then add reduced vitamin C (Vc), the concentration is 4% (wt%), and Vc needs to be prepared and used now;
[0032] (2), adding the silicon carbide nano-whiskers through surface cleaning into the solution obtained in step 1, ultrasonically dispersed for 15 minutes; the content of silicon carbide whiskers in the resulting mixture is 25%; the cleaning process is to Silicon nano whiskers were soaked in hydrochloric acid for 3 hours, and then washed with deionized water until the pH was 7;
[0033] (3), the arginine of concentration 10% is added in the mixture that step 2 obtains; The amount of the added arginine makes the pH value of solution be 9, subsequently adds a certain amount of zinc chloride and sulfur in mixed sol...
