New graphene aerogels can be fabricated by vacuum/air drying, and because of the mechanical robustness of the graphene aerogels, shape‐memory polymer/graphene hybrid foams can be fabricated by a simple infiltration‐air‐drying‐crosslinking method. Due to the superelasticity, high strength, and good electrical conductivity of the as‐prepared graphene aerogels, the shape‐memory hybrid foams exhibit excellent thermotropical and electrical shape‐memory properties, outperforming previously reported shape‐memory polymer foams.
