摘 要: | 利用CO_2响应性的含芘聚合物(PNDV)作为分散剂,通过π-π共轭作用力成功附着在石墨烯表面,从而制得一种稳定的石墨烯分散体系。采用UV-Vis、IR、荧光光谱和透射电子显微镜对体系中石墨烯的分散性和CO_2响应性能进行表征。结果表明:PNDV可修饰在石墨烯表面,形成含芘聚合物和石墨烯的杂化体(PNDV-RGO),得到稳定均匀的石墨烯分散溶液。透射电镜显示石墨烯在体系中以单片层形式分布,最大宽度约1μm。在交替通入CO_2/N2后,PNDV-RGO杂化体表现出明显的分散/聚集现象。

Abstract: | The stable graphene dispersion system was prepared using CO 2-response pyrene-contained polymer as a dispersant , which adsorbed on graphene ' s surface viaπ-πconjugate action .The dispers-ibility and CO2-response performance of graphene system were characterized by UV-Vis, IR, fluores-cence and transmission electron microscope .The results showed that pyrene-contained polymer could adsorb on graphene′s surface , so it could form PNDV-RGO complex and the stable graphene dispersion was obtained .The single-layer graphene with 1μm in width could be seen by transmission electron mi-croscope.Furthermore, after bubbling CO2/N2 in turn, graphene in system indicated dispersion/aggre-gation phenomena . |
