Embodiment 1
[0019] A preparation method of antibacterial gel for female vaginal external use, comprising the following steps:
[0020] (1) Add the multi-walled carbon nanotubes to the sulfuric acid solution, and after ultrasonic treatment for 40 minutes, remove two-thirds of the solution by rotary evaporation to obtain a modified multi-walled carbon nanotube suspension, wherein the molar concentration of the sulfuric acid solution is 0.1mol / L, every gram of multi-walled carbon nanotubes was added to 3ml of sulfuric acid solution;
[0021] (2) In parts by weight, 12 parts of N,N-dimethylaminoethyl acrylate, 17 parts of diethylene glycol dimethacrylate, 38 parts of hydroxyethyl methacrylate, 3 parts of modified multi-walled carbon nano Tube suspension, 0.1 part of dicumyl peroxide, and 0.05 part of tetramethylethylenediamine are mixed evenly to prepare a precursor solution, and after adding an initiator to the precursor solution, after mixing evenly, add it to the mold and let it stand The...

[0024] A preparation method of antibacterial gel for female vaginal external use, comprising the following steps:
[0025] (1) Add the multi-walled carbon nanotubes to the sulfuric acid solution, and after ultrasonic treatment for 45 minutes, remove two-thirds of the solution by rotary evaporation to obtain a suspension of modified multi-walled carbon nanotubes, wherein the molar concentration of the sulfuric acid solution is 0.1mol / L, every gram of multi-walled carbon nanotubes was added to 4ml of sulfuric acid solution;
[0026] (2) In parts by weight, 16 parts of N,N-dimethylaminoethyl acrylate, 18 parts of diethylene glycol dimethacrylate, 40 parts of hydroxyethyl methacrylate, 5 parts of modified multi-walled carbon nano Tube suspension, 0.2 parts of benzoyl peroxide, and 0.07 parts of tetramethylethylenediamine are mixed evenly to prepare a precursor solution. After adding an initiator to the precursor solution, mix it evenly, add it to the mold, and let it stand for tre...
Embodiment 3
[0029] A preparation method of antibacterial gel for female vaginal external use, comprising the following steps:
[0030] (1) Add the multi-walled carbon nanotubes to the sulfuric acid solution, and after ultrasonic treatment for 50 minutes, remove two-thirds of the solution by rotary evaporation to obtain a modified multi-walled carbon nanotube suspension, wherein the molar concentration of the sulfuric acid solution is 0.1mol / L, every gram of multi-walled carbon nanotubes was added to 5ml of sulfuric acid solution;
[0031] (2) In parts by weight, 18 parts of N,N-dimethylaminoethyl acrylate, 20 parts of diethylene glycol dimethacrylate, 44 parts of hydroxyethyl methacrylate, 6 parts of modified multi-walled carbon nano Tube suspension, 0.3 parts of di-tert-butyl peroxide, and 0.08 parts of tetramethylethylenediamine were mixed uniformly to prepare a precursor solution. After adding an initiator to the precursor solution, after mixing uniformly, added to the mold, and static...
