Embodiment 1
[0018] A preparation method of layer-by-layer self-assembled polyaniline / nylon composite conductive fabric. First, the nylon fabric is treated with 20g / L sodium polystyrene sulfonate, two dipping and two rolling, the dipping time is 10min, and the rolling ratio is 70% , and dried at 60°C; then soak the treated cotton cloth in a mixed solution with an aniline concentration of 0.1mol / L, ammonium persulfate concentration of 0.1mol / L, and p-toluenesulfonic acid concentration of 0.2mol / L, stirring continuously, and reacting Take it out after 20 minutes, fully wash and dry; finally do a second doping in 1mol / L hydrochloric acid solution for 30 minutes, after washing and drying, the polyaniline / nylon composite conductive fabric is obtained, and its conductivity is 1.7×10 -5 S / cm.
Embodiment 2
[0020] A preparation method of layer-by-layer self-assembled polyaniline / nylon composite conductive fabric. First, the nylon fabric is treated with 20g / L sodium polystyrene sulfonate, two dipping and two rolling, the dipping time is 10min, and the rolling ratio is 70% , drying at 60°C; then soak the treated cotton cloth in a mixed solution with an aniline concentration of 0.05mol / L, ammonium persulfate concentration of 0.05mol / L, and p-toluenesulfonic acid concentration of 0.2mol / L, stirring continuously, and reacting Take it out after 24 minutes, fully wash and dry; finally do a second doping in 1mol / L toluenesulfonic acid solution for 30 minutes, and after washing and drying, you can get a polyaniline / nylon composite conductive fabric with a conductivity of 1.5×10 -5 S / cm.
Embodiment 3
[0022] A preparation method of layer-by-layer self-assembled polyaniline / nylon composite conductive fabric. First, the nylon fabric is treated with 20g / L sodium polystyrene sulfonate, two dipping and two rolling, the dipping time is 10min, and the rolling ratio is 70% , drying at 60°C; then immerse the treated nylon fabric in a mixed solution with aniline concentration of 0.1mol / L, ammonium persulfate concentration of 0.1mol / L, and p-toluenesulfonic acid concentration of 0.3mol / L, stirring continuously, After reacting for 24 minutes, take it out, fully wash it and dry it; finally, carry out secondary doping in 1mol / L hydrochloric acid solution for 30 minutes, after washing and drying, you can get a polyaniline / nylon composite conductive fabric with a conductivity of 7×10 -5 S / cm.
