摘要
采用改进的Hummers法制备氧化石墨烯,将二维材料氧化石墨烯浸泡在聚乙烯醇溶液中,得到氧化石墨烯/聚乙烯醇复合膜。光学显微镜、扫描电镜、红外光谱等表征结果表明,浸泡24h后可得到平滑、平整的氧化石墨烯/聚乙烯醇复合膜,PVA向GO层的渗透作用提高了氧化石墨烯的层间距。
In this paper, graphene oxide was prepared by modified Hummers method. Simple immersion of graphene oxide film in polyvinyl alcohol solution, prepared graphene oxide/polyvinyl alcohol composite film. The physico-chemical changes in the resulting composite membranes were investigated using optical microscopy(OM), fourier transform infrared spectrometer(FT-IR)and scanning electron microscope(SEM). It showed that a smooth graphene oxide/polyvinyl alcohol composite film can be obtained after 24 hours immersion. The penetration of PVA into GO layer increased the interlayer spacing of graphene oxide.
