本发明公开了种磺化氧化石墨烯/二氧化锡/聚吡咯复合材料的制备方法。以水热法在氧化石墨烯片层间沉积二氧化锡颗粒，制备三维氧化石墨烯/二氧化锡复合物胶体，并用氨基苯磺酸对制备的胶体进行磺化，然后采用界面聚合法在磺化的三维氧化石墨烯/二氧化锡复合物上面包覆聚吡咯制备磺化氧化石墨烯/二氧化锡/聚吡咯三维多孔网状复合材料。本发明方法制备过程简单、绿色环保、可靠，且所制得的磺化氧化石墨烯/二氧化锡/聚吡咯复合材料为三维多孔网状，具有规整的空间结构、高能量密度和功率密度、优秀的循环性能，是种理想的超级电容器电极材料，尤其适合工业化生产。 The invention discloses a preparation method for a sulfonated graphene oxide/stannic dioxide/polypyrrole composite material. Stannic dioxide granules are deposited in graphene oxide sheet interlayer by a hydrothermal method to prepare three-dimensional graphene oxide/stannic dioxide compound colloid; sulfonating on the prepared colloid is performed by aminobenzene sulfonic acid; and next, the sulfonated three-dimensional graphene oxide/stannic dioxide compound is coated with polypyrrole by adopting an interface polymerization method to prepare the sulfonated graphene oxide/stannic dioxide/polypyrrole three-dimensional porous net-shaped composite material. The preparation method is simple in process, green and environment-friendly, and reliable; and
