In this paper, poly(1,5-diaminonaphthalene) was interpenetrated into the network made of multiwalled carbon nanotubes (MWCNT) on platinum interdigital electrode (IDE) by electro-polymerization of 1,5-diaminonaphthalene (1,5-DAN). The electro-polymerization process of 1,5-DAN on MWCNT was controlled by scanning the cyclic voltage at 50 mV s(-1) scan rate between -0.1 V and +0.95 V vs. saturated calomel electrode (SCE). The results of voltammetric responses and Raman spectroscopy represented that the films MWCNT/poly(1,5-DAN) were successfully created by this polymerization process. The films MWCNT/poly(1,5-DAN) were investigated for gas-sensing to NO2 at low concentration level. The gas-sensing results showed that the response-recovery times were long and strongly affected by thickness of the film MWCNT/poly(1,5-DAN). Nevertheless, these films represented auspicious results for gas sensors operating at room temperature.
本文通过在铂叉指电极（IDE）上的多壁碳纳米管（MWCNT）网络中进行 1,5-二氨基萘（1,5-DAN）的电聚合，将聚 1,5-二氨基萘（poly(1,5-DAN)）互穿到该网络中。1,5-DAN 在 MWCNT 上的电聚合过程通过在相对于饱和甘汞电极（SCE）的-0.1 V 和+0.95 V 之间以 50 mV s(-1)的扫描速率扫描循环电压来控制。伏安响应和拉曼光谱的结果表明，通过该聚合过程成功地制备了 MWCNT/聚（1,5-DAN）薄膜。研究了 MWCNT/聚（1,5-DAN）薄膜对低浓度 NO2 的气敏性能。气敏结果表明，响应-恢复时间较长，并且强烈受到薄膜 MWCNT/聚（1,5-DAN）厚度的影响。然而，这些薄膜对于在室温下工作的气体传感器表现出良好的结果。
