Embodiment 1
[0051] (1) Prepare benzalkonium bromide solution with a mass concentration of 50 mg / mL;
[0052] (2) Prepare a graphene oxide (GO) aqueous solution with a concentration of 4 mg / mL, and the pH is about 0.74;
[0053] (3) Take 1 mL, 4 mg / mL GO solution, and quickly add it to a test tube containing 200 μL benzalkonium bromide solution of the corresponding concentration to obtain a brown benzalkonium bromide / graphene oxide antibacterial gel.
[0054] The prepared brown benzalkonium bromide / graphene oxide gel was as figure 2 As shown in figure a. Obviously, from the appearance point of view, a brown gel was prepared, that is, graphene oxide was not reduced. From left to right, the concentrations of benzalkonium bromide are 50mg / mL, 30mg / mL, and 10mg / mL. This can be compared with the antibacterial gel with dopamine added. The antibacterial gel with dopamine added is black because of the self-polymerization and reduction properties of dopamine itself, and the graphene oxide is re...
Embodiment 2
[0061] (1) Prepare benzalkonium bromide solution with a mass concentration of 30 mg / mL;
[0062] (2) Prepare a graphene oxide (GO) aqueous solution with a concentration of 4 mg / mL, and the pH is about 0.74;
[0063] (3) Take 1 mL, 4 mg / mL GO solution, and add it to a test tube containing 200 μL benzalkonium bromide solution of the corresponding concentration to obtain a brown benzalkonium bromide / graphene oxide antibacterial gel.
[0064] The prepared brown benzalkonium bromide / graphene oxide gel was as figure 2 As shown in figure b.
Embodiment 3
[0066] (1) Prepare benzalkonium bromide solution with a mass concentration of 10 mg / mL;
