    摘要
  • 摘要: 通过原位乳化聚合制备了不同膨胀石墨含量（1%、2%、3%和4%质量分数）的聚丙烯腈-聚甲基丙烯酸甲酯共聚物/膨胀石墨纳米复合材料。通过紫外-可见和傅里叶变换红外光谱验证了共聚物及纳米复合材料结构的形成。用X射线衍射、扫描电镜、透射电镜研究了膨胀石墨在聚合物基体中的分散性及其形貌。用热重考察了复合材料的耐热稳定性，同时也考察了复合材料的电导特性及其阻抗随膨胀石墨含量的变化规律。研究表明，随着复合材料中石墨含量的增加，复合材料的氧气密性和热稳定性获得较大程度的改善。
    Abstract: Expanded graphite/polyacrylonitrile-co-poly (methyl methacrylate) (EG/PAN-co-PMMA) composites were prepared by the incorporation of EG at various concentrations (1, 2, 3, and 4%, w/w) into PAN-co-PMMA by an in situ emulsifier-free emulsion polymerization method. As-synthesized composites were characterized by UV/VIS and FT-IR, XRD, SEM, TEM and TGA. The thermal stability of the copolymer was significantly improved by the addition of EG. The oxygen permeabilities of the composites were substantially reduced and the electrical conductivities of the composites were significantly increased by increasing the EG content.
