Conducting poly(o-phenylenediamine) (POPD)/graphene oxide (GO) composites were prepared using a facile and efficient method involving the in-situ polymerization of OPD in the presence of GO in an aqueous medium. Copper sulfate was used as an oxidative initiator for the polymerization of OPD. Scanning electron microscopy and transmission electron microscopy images showed that POPD microfibrils were formed and distributed relatively uniformly with GO sheets in the obtained composites. X-ray diffraction results revealed the highly crystal structure of POPD. This composite exhibited good catalytic activity and stability. These results highlight the potential applications of POPD/GO composites as excellent electrochemical sensors. The composites were used to modify glass carbon electrodes for the chemical detection of hydrogen peroxide in aqueous media.
采用一种简便高效的方法制备了导电聚(邻苯二胺)(POPD)/氧化石墨烯(GO)复合材料,该方法包括在水介质中,在GO存在的情况下对OPD进行原位聚合。硫酸铜用作OPD聚合的氧化引发剂。扫描电子显微镜和透射电子显微镜图像显示,在所得复合材料中形成了POPD微纤维,并且与GO片相对均匀地分布。X射线衍射结果揭示了POPD的高晶体结构。该复合材料表现出良好的催化活性和稳定性。这些结果突出了POPD/GO复合材料作为优异电化学传感器的潜在应用。该复合材料用于修饰玻碳电极,以对水介质中的过氧化氢进行化学检测。
