新方法合成聚芳双硫醚/石墨导电纳米复合材料(英文)

Novel Synthesis of Conductive Poly (arylene disulfide) /Graphite Nanocomposite

利用氧化石墨的氧化性及其在碱性水溶液中剥离分散的性质,将其与芳香二硫酚在碱性水溶液中反应,合成了聚芳双硫醚/石墨导电纳米复合材料。XRD及TEM均证明了无机片层在聚合物基体中呈剥离分散状态。电导率测试表明所合成的纳米复合材料的电导率较氧化石墨提高了近7个数量级。

A new process for the dispersion of graphite in the form of nanosheets in a poly(arylene disulfide) matrix was developed via in situ polymerization of monomer at the presence of exfoliated graphite oxide in NaOH solution. The nanoscale dispersion of graphite layers within poly(arylene disulfide) was confirmed by the X-ray diffraction patterns and TEM examinations. According to the conductivity test, the conductivity of the final poly(arylene disulfide)/graphite nanocomposite was increased by about 7 orders of magnitude compared with GO.
