石墨烯具有较大的理论比表面积、优异的导电性、力学性能、化学稳定性和热稳定性[[1]，[2],[3],[4],[5],[6],[7]]，广泛应用于超级电容器、锂硫电池和废水处理等领域。石墨烯是由sp - 2杂化碳原子[8]键合而成的蜂窝状二维晶体材料。作为石墨烯衍生物的氧化石墨烯（GO）是一种具有完整石墨区b[9]的层状材料。氧化石墨烯基聚合物基体由于其与聚合物的相容性以及聚合物基体的力学、热学和电学性能的改善，比其他纳米填料基聚合物基体要好得多。然而，当石墨烯应用于这些领域时，由强π-π相互作用和范德华力引起的团聚和堆积现象阻碍了石墨烯优异性能的发挥，严重影响了其实际应用性能[11]。最有效的方法是设计一种石墨烯材料，它可以将单个石墨烯片粘合在一起形成三维网络结构，从而避免单个石墨烯片的再堆积和不可逆聚集[[12]，[13],[14]]。石墨烯气凝胶（GA）也被称为石墨烯泡沫[15]、石墨烯海绵[16]和石墨烯宏观结构[17]。文献报道的典型三维石墨烯网络包括石墨烯泡沫、石墨烯海绵和石墨烯气凝胶。泡沫镍首次作为模板用于石墨烯泡沫[18]的合成。因此，泡沫石墨烯继承了泡沫镍的微孔结构，具有连续互联的石墨烯三维网络。石墨烯海绵具有与石墨烯泡沫类似的多孔结构。然而，石墨烯片部分排列或几乎平行，形成各向异性层状结构。石墨烯海绵因其类似海绵[19]的高效可回收吸收性能而得名。GA通常采用溶胶-凝胶化学法制备。主要工艺是还原氧化石墨烯形成高交联石墨烯水凝胶，然后冷冻干燥或超临界干燥去除吸附水分[20,21]。
Graphene is widely used in supercapacitors, lithium sulfur batteries and wastewater treatment due to its large theoretical specific surface area, excellent electrical conductivity, mechanical properties, chemical stability and thermal stability [[1],[2],[3],[4],[5],[6],[7]]. Graphene is a honeycomb two-dimensional crystal material formed by the bonding of sp 2 hybrid carbon atoms [8]. Graphene oxide (GO) as graphene-derivative is a layered material with intact graphitic regions [9]. GO-based is much better than other nano-filler-based polymer matrix due to its compatibility with polymers and also improvements in mechanical, thermal, and electrical properties of polymeric matrices [10]. However, when graphene is applied to these fields, the agglomeration and stacking phenomenon caused by strong π-π interaction and van der Waals force hinder the exertion of graphene's excellent properties and seriously affect its practical application performance [11].The most effective method is to design a graphene material, which can bond single graphene sheets together to form a 3D network structure, so as to avoid the restacking and irreversible aggregation of single graphene sheets [[12],[13],[14]]. Graphene aerogels (GA) are also called graphene foams [15], graphene sponge [16] and graphene macrostructure [17]. The typical 3D graphene networks reported on the literature include graphene foam, graphene sponge and graphene aerogel. Foam nickel was first used as template for synthesis of graphene foam [18]. Therefore, graphene foam inherits the microporous structure of foamed nickel and has a continuous and interconnected graphene 3D network. Graphene sponge has a porous structure similar to that of graphene foam. However, graphene sheets are partially aligned or almost parallel, forming anisotropic layered structures. Graphene sponge is named for its high efficiency and recyclable absorption performance similar to sponge [19]. GA is usually prepared by sol-gel chemical process. The main process are reduced graphene oxide to form highly crosslink graphene hydrogels, then freeze-dried or supercritical drying to remove absorbed water [20, 21].
