Graphene aerogel-phase change material host-guest smart films

A graphene aerogel (GA)-phase change material (PCM) host-guest film (GAPHF) was developed. The GAPHF overcame the intrinsic brittleness of PCMs in the solid state and fluidity of PCMs in the melted state simultaneously. The densified GA film was fabricated through the press-forging process of unidirectional GA fiber arrays.
