摘要：

为得到导电性能优良的涤纶织物,在紫外线辐照下通过原位聚合法制备聚吡咯/银导电涤纶织物。探讨了AgNO3浓度、十二烷基苯磺酸钠(SDBS)浓度、聚乙烯吡咯烷酮(PVP)浓度和反应时间对聚吡咯/银(PPy/Ag)导电涤纶织物导电性能的影响,并探究其最佳制备工艺。结果表明:当低温真空等离子体处理功率为220 W,处理时间为4 min,AgNO3浓度为0.4 mol/L,SDBS浓度为0.02 mol/L,PVP浓度为0.8 mol/L,反应时间为8 h时,所制得的导电涤纶织物表面方阻最小,为61.54 Ω/□,且表面具有1层连续的聚吡咯导电薄膜;导电涤纶织物表面存在纳米银颗粒,其具有良好的抗菌性,对大肠杆菌和金黄色葡萄球菌的抑菌带宽度均大于1 mm。

Abstract:

In order to obtain excellent electrical conductivity for a polyester fabric, a polypyr-role/silver (PPy/Ag) conductive polyester fabric was prepared by in-situ polymerization with ultraviolet exposure. The effects of AgNO3 concentration, sodium dodecylbenzene sulfonate(SDBS) concentration, polyvinylpyrrolidone(PVP) concentration and reaction time on the electrical conductivity of PPy/Ag conductive polyester fabric were investigated and the optimal preparation process was explored. The results show that when the low temperature vacuum plasma treatment power is set to 220 W, the treatment time is 4 min, the AgNO3 concentration is 0.4 mol/L, the SDBS concentration is 0.02 mol/L, the PVP concentration is 0.8 mol/L, the reaction time is 8 h, the composite fabric obtains the smallest sheet resistance, which is 61.54 Ω/□. There forms a continuous polypyrrole conductive film on the surface. The composite fabric demonstrats good antibacterial properties due to the presence of nano silver particles on surface and the width of the antibacterial band of escherichia coli and staphylococcus oureus is greater than 1 mm.

Key words: ultroviolet exposure, polypyrrole, conductive polyester fabric, in-situ polymerization, nano silver particle, antibacterial property
