重点对利用亲核取代和缩合反应实现氧化石墨烯共价键功能化修饰的研究进展进行了综述，分析了各种共价键功能化修饰方法的运用，对氧化石墨烯在常用溶剂中的分散稳定性及其与聚合物基体相容性的促进作用。基于氧化石墨烯具有比石墨烯更易于进行共价键功能化修饰的优势，进一步论述了经共价键功能化修饰后的氧化石墨烯对聚氨酯和丙烯酸树脂等聚合物改性的效果，同时对功能化修饰氧化石墨烯在皮革涂饰剂改性中的应用前景进行了展望。

The research progress of covalent functional modification of graphene oxide with nucleophilic substitution and condensation reactions was emphatically reviewed. The roles of various covalent functional modification methods to improve the dispersion stability of graphene oxide in common solvents and the promotion of compatibility with the poly- mer matrix were analyzed. Since graphene oxide has the advantage of easier covalent functional modification than gra- phene, the effects of functionalized graphene oxide on the polymer modification of polyurethane and acrylic resin were further discussed. The application prospect of the covalently functionalized graphene oxide in leather finishing agent modification was also prospected.
