Description

石墨烯聚(5-醛基吲哚)纳米复合材料的制备
技术领域
本发明涉及石墨烯聚(5-醛基吲哚)纳米复合材料的制备，属于材料化学领域。
背景技术
顺应研究需要，各种电致变色材料也相继被发现，如聚噻吩、聚吡咯、聚咔唑等。聚吲哚家族因其独特优势得到了人们的关注，特别是热稳定性好、电致发光性能稳定、氧化还原活性高等。一般来说，在聚合难易程度上，导电聚合物单体中有反应活性功能基团的要比没有取代基团的更易反应；在电致变色性能上，一般由掺杂决定。为了改善其稳定性，近年来人们对该材料的研究主要集中在降低共轭聚合物的能带间隙上，其中一个常用方法是向聚合物中加入π共轭链，例如苯基或者噻吩基。
聚(5-醛基吲哚)分子中既有苯环也有吲哚环，苯环的加入使分子的共轭平面结构增大，这不仅有利于电子在三环系统中的苯环上传输，而且还使分子能带间隙降低，相应的聚合物具有良好的电致变色性能。高性能的电致变色材料仍然是科学家们的主要目标，到目前为止，没课题组做关于聚(5-醛基吲哚)/石墨烯电化学合成及其电致变色性能的研究。基于此，将尝试通过直接阳极氧化聚(5-醛基吲哚)单体和石墨烯，在电极表面电沉积得到聚(5-醛基吲哚)/石墨烯膜，并对聚合物的电致变色性能和动力学性能进行表征。
发明内容
本发明所要解决的技术问题是提供石墨烯聚(5-醛基吲哚)纳米复合材料的制备，技术方案如下：首先，在0.5-0.7mg/mL氧化石墨烯的水溶液中采用一室三电极体系中进行石墨烯的电化学沉积，沉积电压为-1.8V，至此，化学还原的氧化石墨烯被修饰在了ITO导电玻璃上；然后，在含0.1-0.3mol L-1TBATFB的乙腈溶液中采用一室三电极体系，工作电极为化学还原的氧化石墨烯修饰的ITO导电玻璃，使0.02-0.04mol L-15-醛基吲哚1.35V的电压下进行电化学聚合，从而制备石墨烯聚(5-醛基吲哚)纳米复合材料。
本发明的有益效果是：制备工艺简易环保，成本低，适用范围广。
