摘要：

为拓展聚吡咯/银(PPy/Ag)导电涤纶织物的应用领域,在等离子体预处理涤纶织物的条件下,以硝酸银为氧化剂,采用一锅法制备PPy/Ag导电涤纶织物。借助傅里叶红外光谱仪、X 射线衍射仪和扫描电子显微镜等对导电织物进行表征,通过电阻仪测试导电织物的方阻值,采用琼脂平皿法测试其抑菌效果。结果表明:制备的PPy/Ag导电涤纶织物具有良好的导电性,并对大肠杆菌和金黄色葡萄球菌具有明显的抑制作用;导电织物的导电性与等离子体预处理涤纶织物的次数呈正相关,且在等离子体预处理4次时,其方阻达到最小值0.22 kΩ/□。

Abstract:

In order to expand the application of polypyrrole/silver (PPy/Ag) conductive polyester fabrics, PPy/Ag conductive polyester fabrics were prepared by one-pot method with silver nitrate as oxidant under the condition of plasma pretreatment. The conductive fabrics were characterized by Fourier transform infrared spectroscopy, X-ray diffraction and scanning electron microscopy. The square resistance of conductive fabrics was measured by resistometer and the bacteriostatic effect was tested by agar plate method. The results show that the PPy/Ag conductive polyester fabrics prepared in this study have good conductivity, and have obvious inhibitory effect on Escherichia coli and Staphylococcus aureus. The conductivity of such fabrics is positively correlated with the number of times of plasma pretreatment to polyester fabrics, and the square resistance of conductive fabrics reaches the minimum value of 0.22 kΩ/□ when the number of plasma pretreatment is 4.

Key words: conductive fabric, polypyrrole, silver nanoparticles, plasma pretreatment, polyester, conductivity, antimicrobial property
