摘要
采用Hummers法制备高氧化程度的氧化石墨烯,并用异氰酸苯酯对其修饰,丙烯腈单体在氧化石墨烯插层并进行原位聚合.采用FT-IR、XRD、TG及SEM对其复合材料的化学结构、结晶度变化、热稳定性及形貌进行了表征.
Graphene oxide （GO） was prepared from flake graphite through liquid oxidation based on Hummers method. Graphene oxide was modified on its surface through the reaction with phenylisocyanate. And with azobisiobutyronitrile（AIBN） as the initator, polyaerylonitrile-GO composite material （GO-PAN） was made by in-situ polymerization of polyaerylonitrile （PAN） between layers of PAN. The performance and structure of GO-PAN were investigated with FT-IR, TG, XRD and SEM.
