| 摘 要： | 以二硫化钼为核,聚苯乙烯为壳,通过种子乳液聚合方法,成功制备了具有核壳结构的聚苯乙烯/二硫化钼(PS/MoS2)有机-无机纳米复合微球。利用紫外可见吸收光谱、透射电镜、扫描电镜、能量色散谱仪等多种方法,对PS/MoS2纳米微球的形貌、结构进行了表征,同时,利用分散性试验考察了PS/MoS2纳米微球在油溶性单体双环戊二烯(DCPD)中的分散性。试验结果表明:聚苯乙烯包覆在MoS2的表面,形成核壳结构;纳米粉体呈球形且粒径尺寸均一。分散性试验表明PS/MoS2纳米微球在DCPD中具有极佳的分散性。

| Abstract: | Molybdenum disulfide (MoS2) nanoparticles and polystryrene (PS) were used as core and shell.The polystyrene/molybdenum disulfide (PS/MoS2) organic-inorganic nanocomposite microspheres with core-shell structure were prepared by seed emulsion polymerization.Its morphology and structure were characterized by UV-Vis,TEM,SEM,EDX,etc.and the dispersibility of PS/MoS2 nanocomposite microspheres in the oil-soluble monomer dicylopentadiene (DCPD) was tested.The results indicate that polystyrene (PS) is coated on the surface of MoS2 and the core-shell structure is formed.The PS/MoS2 nanocomposites present microsphere morphology and their particle sizes are monodisperse.The dispersion results show that the PS/MoS2 microspheres have a good dispersibility in DCPD. |
