Two dimensional MoS₂ acting as reinforcing fillers had attracted intense interests in recent years. However, the homogeneous dispersion of MoS₂ nanosheets in polymer matrix and exact interface control were still difficult to achieve due to potent van der Waals forces and surface inactiveness. In this work, hierarchical [email protected]₂ core-shell structures were constructed by combining latex technology and self-assembly of oppositely charged MoS₂ nanosheets onto the surface of polystyrene spheres. The formed core-shell structures were characterized by X-ray diffraction, Fourier transform infrared, thermogravimetric analysis, scanning electron microscopy, transmission electron microscopy and further employed as reinforcing fillers in a host polystyrene matrix by solvent blending method. It was clearly observed that the construction of [email protected]₂ core-shell structures not only improved the dispersion of MoS₂ in the matrix and the interfacial adhesion between MoS₂ and polystyrene, but also obviously improved the thermal stability and fire safety of polystyrene. The method proposed here had proved to be an efficient and facile approach to fabricate polymer/MoS₂ nanocomposites with good dispersion and markedly improved properties.

近年来，作为增强填充剂的二维MoS ₂引起了人们的浓厚兴趣。然而，由于有效的范德华力和表面惰性，仍难以实现MoS ₂纳米片在聚合物基质中的均匀分散和精确的界面控制。在这项工作中，通过结合乳胶技术和带相反电荷的MoS _2的自组装，构建了分层的[受电子邮件保护的] ₂核-壳结构。纳米片到聚苯乙烯球的表面上。通过X射线衍射，傅立叶变换红外，热重分析，扫描电子显微镜，透射电子显微镜对形成的核-壳结构进行表征，并通过溶剂共混法将其进一步用作主体聚苯乙烯基质中的增强填料。可以清楚地看到，[电子邮件保护的] ₂核-壳结构的构建不仅改善了MoS ₂在基体中的分散性和MoS ₂与聚苯乙烯之间的界面粘合性，而且还明显改善了聚苯乙烯的热稳定性和防火安全性。事实证明，这里提出的方法是一种高效且简便的方法来制造聚合物/ MoS ₂ 具有良好分散性和显着改善的性能的纳米复合材料。
