Carbon fiber fabric was treated with radiofrequency plasma in a N₂/H₂ gas mixture to create functional groups with –NH_x or –N, thus promoting conditions for polyaniline (PAni) grafting. The morphology and chemical structure of PAni on the carbon fiber surface were assessed by scanning electron microscopy and Raman spectroscopy, showing strong interactions between the PAni and the carbon fiber, especially for the 5‐min plasma‐treated substrate. The electrochemical activity of electrodes consisting of carbon fiber fabric and PAni was evaluated by cyclic voltammetry and electrochemical impedance spectroscopy, which showed fast polarization response and lower charge transfer resistance for electrodes with better interactions between the PAni and the carbon fiber substrate, indicating the occurrence of grafting.

用于聚苯胺接枝的碳纤维织物的N2-H2等离子体功能化

碳纤维织物在N ₂ / H ₂气体混合物中用射频等离子体处理，以生成带有–NH _x的官能团或-N，从而提高了聚苯胺（PAni）接枝的条件。通过扫描电子显微镜和拉曼光谱对PAni在碳纤维表面的形态和化学结构进行了评估，显示出PAni与碳纤维之间的强相互作用，尤其是经过5分钟等离子体处理的基材。通过循环伏安法和电化学阻抗谱法评估了由碳纤维织物和PAni组成的电极的电化学活性，结果表明电极极化速度快，电荷转移电阻低，且PAni与碳纤维基材之间的相互作用更好，表明发生了碳纳米管和PAni。嫁接。
