Hybrid materials consisting of polymers and graphene are gathering ever‐growing interest. This article reports a novel methodology for preparing chirally helical polyacetylene/graphene hybrid microspheres (MPs) via suspension polymerization in which graphene oxide (GO) or alkynylated GO (MGO) serves as a sole stabilizer. Such polymerizations show remarkable advantages in circumventing the difficulties in usual suspension polymerizations and especially in directly providing clean hybrid MPs. Scanning electron microscopy (SEM), Raman spectra, and electron dispersive spectroscopy indicate that graphene sheets cover the MPs through physical interaction (GO) or covalent bonds (MGO). The hybrid MPs are also characterized by Fourier‐transform infrared spectroscopy (FT‐IR), X‐ray photoelectron spectroscopy, and thermogravimetric analysis. Circular dichroism spectra demonstrate that the polymer chains constituting the MPs adopt predominantly one‐handed helices, endowing the MPs with intriguing optical activity. The established strategy opens a new approach for preparing hybrid MPs constructed by acetylenic polymers and GO.

氧化石墨烯（GO）作为稳定剂，通过悬浮聚合制备手性螺旋聚乙炔/ GO杂化微球

由聚合物和石墨烯组成的混合材料越来越引起人们的关注。本文报道了一种通过悬浮聚合制备手性螺旋聚乙炔/石墨烯杂化微球（MPs）的新颖方法，其中氧化石墨烯（GO）或炔基化GO（MGO）充当唯一的稳定剂。此类聚合在克服常规悬浮聚合中的困难方面，尤其是在直接提供清洁的混合MP方面显示出显着的优势。扫描电子显微镜（SEM），拉曼光谱和电子分散光谱表明，石墨烯片材通过物理相互作用（GO）或共价键（M走）。混合MP的特征还在于傅立叶变换红外光谱（FT-IR），X射线光电子能谱和热重分析。圆二色性光谱表明，构成MP的聚合物链主要采用单手螺旋，使MP具有诱人的光学活性。既定的策略为制备由乙炔聚合物和GO构成的杂化MP开辟了新途径。
