摘　　要：以木质素磺酸钠为磺化试剂,制备磺酸基改性氧化石墨烯,然后与环氧树脂复合制备磺酸基改性氧化石墨烯/环氧树脂复合材料,实验结果表明:在环氧树脂中添加磺酸基改性氧化石墨烯进行复合,能够提高环氧树脂的热稳定性及复合材料图层的硬度和附着力,有效提升环氧树脂的防腐蚀性能.Using sodium lignosulfonate as sulfonating agent,sulfonic modified graphene oxide was prepared,and then compounded with epoxy resin to prepare sulfonic modified graphene oxide/epoxy resin composite.The experimental results showed that the thermal stability of epoxy resin,hardness and adhesion of composite layer were improved by compounding sulfonic modified graphene oxide with epoxy resin which improved the corrosion resistance of epoxy resin.
