摘　　要：以水合耕为还原剂,采用自组装法原位制备了还原氧化石墨烯增强丙烯酸酯橡胶(ACM/RGO)。X-射线衍射和X-射线光电子能谱表征了RGO的化学结构,透射电镜和扫描电镜表明RG0均匀分散在ACM基体中。与纯ACM相比,ACM/RG0的耐热性和耐水性得到了明显改善,这主要归因于RGO片层的阻隔作用。同时,RG0对ACM有显著的增强作用。当RGO的加入量为2phr时,增强ACM的拉伸强度达到18.8MPa,远高于纯ACM的3.5MPa,且断裂伸长率降幅不明显。Reduced graphene oxide reinforced acrylate rubber(ACM/RG0)was in situ prepared via self-assembly method in the presence of hydrazine hydrate as reducing agent.X-ray diffraction and X-ray photoelectron spectroscopy were utilized to characterize the chemical structure of RGO,and transmission electron microscope and seanning electron microscope demonstrated that RGO was uniformly dispersed in ACM matrix.Due to the barrier property of RGO sheets,the resistances to heat and water of ACM/RGO were obviously improved.Meanwhile,RGO had significant reinforcement role for the pure ACM.With 2 phr of RGO,the tensile strength of ACM/RGO reached 18.8 MPa,which was far higher than that of ACM at 3.5 MPa,and the elongation at break decreased little.
