The hybrid antistatic agent SCNTs/OAA composed of sulfonated carbon nanotubes (SCNTs) and organic antistatic agent (OAA) was treated on the fiber surface to construct the hybrid conductive layer. Among them, SCNTs were synthesized through a simple method, and their chemical structure and morphology were characterized. SCNTs had good dispersibility due to the presence of sulfonic acid groups, which made SCNTs uniformly dispersed on the fiber surface. The SCNTs/OAA-treated fiber was hardly affected by relative humidity, because SCNTs form a continuous and uniform physical conductive network on the fiber surface. When the addition amount of SCNTs/OAA was 0.5~2 wt%, the fiber had excellent antistatic ability. Under the synergistic effect of SCNTs and OAA, the resistivity of SCNTs/OAA-treated fiber was almost not affected by fiber stretching.
由磺化碳纳米管（SCNTs）和有机抗静电剂（OAA）组成的杂化抗静电剂SCNTs/OAA被处理在纤维表面以构建杂化导电层。其中，SCNTs通过一种简单的方法合成，并对其化学结构和形态进行了表征。由于磺酸基团的存在，SCNTs具有良好的分散性，这使得SCNTs均匀地分散在纤维表面。经SCNTs/OAA处理的纤维几乎不受相对湿度的影响，因为SCNTs在纤维表面形成了连续且均匀的物理导电网络。当SCNTs/OAA的添加量为0.5~2 wt%时，纤维具有优异的抗静电能力。在SCNTs和OAA的协同作用下，经SCNTs/OAA处理的纤维的电阻率几乎不受纤维拉伸的影响。
