▎ 摘　　要

NOVELTY - Preparation of three-dimensional graphene-copper nanowire composite aerogel comprises taking ethylene glycol and copper nanowire, adding ascorbic acid, dispersing uniformly, mixing with 8 mg/mL graphene oxide aqueous solution to obtain mixed solution, hydrothermally reacting at 160 degrees C for 6 hours, cooling, adding 0.5 wt.% hydrazine hydrate solution, washing for 24 hours and changing hydrazine hydrate solution every 8 hours, and freeze-drying. USE - Method for preparing three-dimensional graphene-copper nanowire composite aerogel. ADVANTAGE - The composite aerogel has three-dimensional porous structure, low density, good compression performance and high conductivity.
