摘要

本文研究了显色双酰胺杯[4]芳烃- swcnts纳米复合薄膜的光学、润湿性、形态学和传感性能。将单壁碳纳米管与5,17-二(苯基偶氮)-26,28 -二{[(乙氧羰基)甲基氨基甲氧基]甲氧基}-25,27-二(乙氧羰基甲氧基)杯芳烃在氯苯中混合制备纳米复合溶液。强调了双酰胺杯芳烃与swcnts之间可能的相互作用,这可能是纳米复合材料某些性能增强的原因。首先,利用紫外可见分光光度计和接触角测量(CAM)对修饰电极的表面进行了表征。纳米碳管在溶液中的负载和加热过程对薄膜性能的影响对纳米碳管基薄膜的光学性能和润湿性起着至关重要的作用。然后用扫描电镜观察碳纳米管掺入前后的形态学变化。最后,利用电化学阻抗谱(EIS)研究了双酰胺杯[4]芳烃- swcnts薄膜包覆金电极对Al3+离子的传感性能。

Surface characterization of bis-amide calix[4]arene doped SWCNT nanocomposite and its application as an electrochemical sensor for the determination of Al3+ ion
This study focuses on the optical, wettability, morphological and sensing properties of the chromogenic bis-amide calix[4]arene-SWCNT nanocomposite thin film. Nanocomposite solution was done by mixing single-walled carbon nanotubes with 5,17-bis(phenylazo)-26,28 bis{[(ethoxycarbonyl)methylcarbamoyl] methoxy}-25,27-di(ethoxycarbonylmethoxy)-calix[4]arene in chlorobenzene. The possible interactions between bis-amide calixarene and SWCNT that may be responsible for enhancement in certain properties of the nanocomposite were highlighted. Firstly, the surface of the modified electrode was characterized by using UV–visible spectrophotometer and contact angle measurement (CAM). The effect of the SWCNT loading in the solution and the heating process on the film properties plays a crucial role in the optical and wettability properties of the CNTs based films. Then, morphological study was examined before and after CNT incorporation by using scanning electron microscopy. Finally, the sensing properties of bis-amide calix[4]arene-SWCNT thin film coated gold electrode were investigated using electrochemical impedance spectroscopy (EIS) toward the detection of Al3+ ion.
