Abstract

This paper reports a large scale production route for polystyrene (PS) nanoparticle-functionalized graphene sheets using water based in situ microemulsion polymerization. The higher surface area of the graphene basal plane and the better proximity of the reactant species in in situ microemulsion polymerization were used to functionalize the graphene sheets using PS nanoparticles. The thermal properties of the PS were improved with the incorporation of graphene in the composite. The modified graphene exhibited good compatibility and interactions with the host PS matrix to form conducting PS films.

摘要

本文报道了一种使用水基原位微乳液聚合大规模制备聚苯乙烯（PS）纳米粒子功能化石墨烯片的方法。通过原位微乳液聚合，利用石墨烯基面的更大表面积和反应物在其中的更好接近程度，将 PS 纳米粒子功能化到石墨烯片上。在复合材料中加入石墨烯后，PS 的热性能得到了改善。改性石墨烯与 PS 基质具有良好的相容性和相互作用，形成了导电 PS 薄膜。
