摘要：

为研究等离子体处理时间对铜/聚吡咯/羊毛复合织物的导电性能,拓展羊毛织物在柔性传感器领域的应用,利用等离子体气相沉积技术对羊毛进行去鳞片化处理,依次对羊毛织物预处理300、600、900、1 200 s,然后在羊毛织物表面原位聚合构建聚吡咯膜层,并用磁控溅射沉积铜薄膜增强纤维表面的导电网络;借助扫描电子显微镜、傅里叶红外光谱仪和热重分析仪等手段表征了铜/聚吡咯/羊毛导电织物的结构和导电性,同时研究了铜/聚吡咯/羊毛导电复合织物的力学性能。结果表明:等离子体处理时间为1 200 s时制备的铜/聚吡咯涂层毛织物具有良好的导电性和力学性能,平均方阻为67.32 Ω/□;经水洗2 h后,铜/聚吡咯涂层毛织物的方阻优于未经等离子体处理的聚吡咯/羊毛织物,耐水洗性能较稳定。

Abstract:

This research was carried out aiming to study the conductivity of Cu/polypyrrole/wool composite fabrics affected by plasma treatment time and to expand the application of wool fabric in the field of flexible sensor. Firstly, the wool fiber descaling was carried out using plasma vapor deposition technology by treating the wool fabric for 300, 600, 900 and 1 200 s treatment time, before a polypyrrole membrane was constructed by in-situ polymerization on the surface of wool fabric. Cu was then deposited by magnetron sputtering(Cu) film enhancing the conductive network on the surface of the fiber. The structure and conductivity of Cu/polypyrrole/wool conductive fabric were characterized by means of scanning electron microscope, Fourier transform infrared spectrometer and thermogravimetric analyzer. The mechanical properties of Cu/polypyrrole/wool conductive composite fabric were also studied. The results show that the Cu/polypyrrole coated wool fabric with treatment time of 1 200 s demonstrates the highest electrical conductivity and mechanical property, and the average square resistance is 67.32 Ω/□. After washing for 2 h, the square resistance of cu/polypyrrole coated wool fabric is better than that of Polypyrrole/wool fabric without plasma treatment, and the washing resistance is stable.

Key words: wool fabric, plasma treatment, polypyrrole, magnetron sputtering, conductivity, flexible sensor
