以辉光放电CF4等离子改性的碳纳米管(CNTs)为原料,不同嵌织比例的纬向嵌织铜丝织物为基底材料,采用喷涂法制成简单的气敏传感器。拉曼光谱、X射线光电子谱(XPS)和扫描电镜分析表明:等离子改性能够显著地增加CNTs中的含氟基团,并且提高了表面的活性位数量,经喷涂后CNTs较均匀的涂覆于涤纶表面。对柔性传感器氨敏测试发现对NH_4具有高度的响应和恢复能力。
Glow discharge CF4 plasma-modified carbon nanotubes (CNTs) as raw materials, different weaving ratio of the weft woven copper fabric as the base material, the use of spray method to make a simple gas sensor. Raman spectroscopy, X-ray photoelectron spectroscopy (XPS) and scanning electron microscopy analysis showed that: plasma modification can significantly increase the fluorine-containing groups in CNTs, and increase the number of active sites on the surface, after spraying CNTs more uniform coating On the polyester surface. Ammonia sensitivities to flexible sensors were found to have a high degree of response and recovery to NH4.
