报道了一种通过大环低聚物原位开环聚合制备聚(4，4‘-二苯氧基二硫化物)/石墨纳米片状复合材料的有效方法。在微波辐射和溶液超声作用下制备了完全剥离的石墨片。在纳米石墨片存在下，通过大环低聚物的原位熔融开环聚合制备了纳米复合材料。用场发射扫描电子显微镜(FE-SEM)、透射电子显微镜(TEM)、拉伸试验机和电导率测试等手段对所制得的石墨片和聚芳二硫醚/石墨纳米复合材料进行了表征。与纯聚合物相比，聚芳二硫醚/石墨纳米复合材料的电导率显著提高，当石墨含量为5wt%时，其电导率约为10−3s/cm。纳米复合材料既是高性能的聚合物材料，又是导电材料。因此，它们在高温导电材料方面具有潜在的应用前景。
An effective method for the preparation of poly(4,4′-oxybis(benzene)disulfide)/graphite nanosheet composites via in situ ring-opening polymerization of macrocyclic oligomers were reported. Completely exfoliated graphite nanosheets were prepared under the microwave irradiation followed by sonication in solution. The nanocomposites were fabricated via in situ melt ring-opening polymerization of macrocyclic oligomers in the presence of graphite nanosheets. The graphite nanosheets and resulted poly(arylene disulfide)/graphite nanocomposites were characterized with field emission scanning electron microscope (FE-SEM), transmission electron microscope (TEM), tensile tester and electrical conductivity measurements. Compared with pure polymer, the electrical conductivity of the poly(arylene disulfide)/graphite nanocomposites were dramatically increased and had a value of about 10−3S/cm for the nanocomposite containing 5wt% graphite. The nanocomposites exhibit as both high performance polymeric material and electrically conductive material. Therefore, they show potential applications as high temperature conducting materials.
