摘　　要：近年来,石墨烯/纤维素复合材料引起了研究者的广泛关注。该材料在透明导电柔性薄膜、电容器、载药、紫外线防护、传感器、吸附等领域有重要的应用价值。本文在收集、归类研究国内外研究者在石墨烯/纤维素复合材料制备方法、性能以及应用工作的基础上,对石墨烯和纤维素复合材料的混合技术、制备方法及应用进行了综述。Graphene is a one-atom-thick planar sheet of sp2-bonded carbon atoms densely packed together in a honeycomb hexagonal lattice. The exceptional structure endows graphene with excellent electrical,mechanical,thermal,and optical properties. Up to now,considerable efforts have been made to explore its application in varied areas,such as catalyst,battery,sensor and etc. Cellulose,one of the most abundant natural polymer on earth,is featured by non-toxicity,renewability,biodegradability and biocompatibility. The hydrophilicity and hydrophobicity,originated from the enriched O-H and C-H,respectively,have made cellulose an ideal candidate for the fabrication of graphene-based materials. So far,graphene / cellulose composites have shown great potential in the applications of transparent conductive flexible films,supercapacitors,drug delivery,UV-protection,sensors,absorbents and so on. In this review,we study the interaction between cellulose materials and graphene materials. Subsequently,the mixing technics,fabrication methods,and application of the graphene / cellulose composites are summarized. Finally,problems,such as dispersion of graphene in cellulose and production efficiency,hampering its up-scale application,have been pointed out.
