Summary: | The invention discloses a preparation method, preparation system and application of graphene aerogel with an oriented structure. The preparation method of the graphene aerogel with the oriented structure comprises the steps of providing graphene oxide dispersion liquid; directly extruding the graphene oxide dispersion liquid through an extrusion mechanism with a hanger type die head to enable the graphene oxide sheet diameter in the graphene oxide dispersion liquid to be subjected to shear stress to form orientation, then carrying out freezing shaping, vacuum drying and reduction treatment on the oriented graphene oxide sheet diameter, and obtaining the graphene aerogel of the oriented structure is obtained. According to the preparation method, the preparation system and the application of the graphene aerogel with the oriented structure, the graphene aerogel with the oriented structure is obtained by extruding the dispersion liquid through shear stress, and the graphene aerogel with the oriented structure wi |
