Embodiment 1
[0018] Dip 4g of wool cloth into pure liquid ammonia for 20, 30, 40, 50 and 60 seconds, then take it out and dry it. Immerse the untreated and liquid ammonia-treated wool cloth into 200mL of pyrrole solution (0.02mol / L) for 20 minutes, stir, and slowly add 20mL of 0.04mol / L ferric chloride solution dropwise for in-situ polymerization. The reaction was maintained for 2 hours. Then the polypyrrole wool conductive cloth was taken out, rinsed with water, and then vacuum-dried at room temperature.
[0019] The surface resistivity of the dried polypyrrole wool conductive cloth was tested, and each sample was tested 5 times, and the average value was taken. The results are listed in Table 1. Higher surface resistivity indicates poorer conductivity. In Table 1, the surface resistivity of polypyrrole wool conductive cloth treated with liquid ammonia is lower than that without liquid ammonia treatment, indicating that liquid ammonia treatment can reduce the surface resistivity of poly...
Embodiment 2
[0023] Soak 4g of wool cloth in pure liquid ammonia for 30 seconds, then take it out and dry it. Immerse the wool cloth treated with liquid ammonia into 200mL of pyrrole solution (0.02mol / L) for 20 minutes, stir, and slowly add 20mL of 0.04mol / L ferric chloride solution dropwise to carry out in-situ polymerization reaction, and the reaction is maintained for 1 , 2, 3, 4, 5 and 6 hours. Then the polypyrrole wool conductive cloth was taken out, rinsed with water, and then vacuum-dried at room temperature.
[0024] The surface resistivity of the dried polypyrrole wool conductive cloth was tested, and each sample was tested 5 times, and the average value was taken. The results are listed in Table 2. Higher surface resistivity indicates poorer conductivity. In table 2, the surface resistivity of the 4-hour sample of the polymerization reaction time is the lowest, although the surface resistivity of the 5-hour and 6-hour sample of the polymerization reaction time is close to the 4...
Embodiment 3
[0028] Soak 4g of wool cloth in pure liquid ammonia for 30 seconds, then take it out and dry it. Immerse the wool cloth treated with liquid ammonia into 200mL of pyrrole solution (0.02, 0.04, 0.06, 0.08 and 0.10mol / L) for 20 minutes, stir, and slowly add 20mL of 0.04, 0.08, 0.12, 0.16 and 0.2mol / L ferric chloride solution (that is, the concentration of the ferric chloride solution is twice the concentration of the pyrrole solution) for in-situ polymerization reaction, and the reaction is maintained for 4 hours. Then the polypyrrole wool conductive cloth was taken out, rinsed with water, and then vacuum-dried at room temperature.
[0029] The surface resistivity of the dried polypyrrole wool conductive cloth was tested, and each sample was tested 5 times, and the average value was taken. The results are listed in Table 3. Higher surface resistivity indicates poorer conductivity. In Table 3, the polypyrrole wool conductive cloth made by polymerization of 0.06mol / L pyrrole solu...
