A conductive hydrogel is a composite conductive material formed by combining a conductive polymer with a nanogel structure of a hydrogel. Conductive hydrogels not only have potential applications in supercapacitors, sensors, and modulators, they can also be synthesized by many methods, such as copolymerization, crosslinking, and grafting. In this work, we successfully prepared three conductive composite hydrogels by polymerization, namely polypyrrole sodium alginate conductive hydrogel, ferric chloride-doped polypyrrole sodium alginate hydrogel and doped polypyrrole sodium alginate hydrogel with sodium dodecylbenzene sulfonate. In addition, a series of characterizations were performed for the three conductive hydrogels described above. The results show that the polypyrrole sodium alginate hydrogel doped with ferric chloride forms a nanofiber network with a more stable structure and better electrochemical performance.
导电水凝胶是一种通过将导电聚合物与水凝胶的纳米凝胶结构相结合而形成的复合导电材料。导电水凝胶不仅在超级电容器、传感器和调制器等方面具有潜在应用，而且还可以通过多种方法合成，如共聚、交联和接枝。在这项工作中，我们通过聚合成功制备了三种导电复合水凝胶，即聚吡咯海藻酸钠导电水凝胶、氯化铁掺杂的聚吡咯海藻酸钠水凝胶和十二烷基苯磺酸钠掺杂的聚吡咯海藻酸钠水凝胶。此外，对上述三种导电水凝胶进行了一系列表征。结果表明，掺杂氯化铁的聚吡咯海藻酸钠水凝胶形成了结构更稳定、电化学性能更好的纳米纤维网络。
