Construction method for preparing oriented graphene aerogel at low cost

The invention discloses a construction method for preparing oriented graphene aerogel at low cost. The method adopts a two-step method to prepare the graphene aerogel with an orientation structure, solves the problems of incomplete orientation, easy damage of a skeleton and wrinkling and agglomeration of graphene sheets in the traditional compression orientation process, utilizes a traditional sol-gel method, adds a foaming agent, and realizes the preparation of the graphene aerogel with the orientation structure. The graphene aerogel with a regular structure is prepared by adopting a low-cost green method without freeze-drying. And subsequently, inducing the graphene sheet layer to be oriented along the direction of vertical force by utilizing uniaxial compression of confinement on two sides, so as to prepare the graphene aerogel with an oriented structure. 本发明公开了一种低成本制备取向石墨烯气凝胶的构筑方法。所述方法采用两步法制备具有取向结构的石墨烯气凝胶，解决传统压缩取向过程中无需骨架取向不完整，骨架易破坏，石墨烯片褶皱团聚问题，利用传统的溶胶-凝胶法，添加发泡剂，采用无需冻干的低成本绿色方法制备具有规整结构的石墨烯气凝胶。后续利用两侧限域的单轴向压缩诱
