▎ 摘　　要

NOVELTY - Graphene oxide aerogel beads (GOABs) comprises a core/shell structure having a smooth shell and a multilayer core, where the smooth shell and the layers of the multilayer core comprise graphene oxide or reduced graphene oxide, and the layers of the multilayer core are separated by 1-50 mu m. USE - The graphene oxide aerogel beads which is used in a device comprising an electromagnetic interference (EMI) shielding film, a solar still, or a thermal management pack (all claimed). The solar thermal aerogel materials is used for practical water purification applications. ADVANTAGE - The aerogel bead allows scalable manufacturing of efficient solar thermal aerogel. The aerogel beads exhibit improved recyclability and use potential. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) a method of preparing GOABs comprising providing an aqueous slurry of graphene oxide, extruding drops into a coagulation bath containing an aqueous solution of a coagulant wherein the GOABs are formed, separating the GOABs from the coagulation bath, washing the GOABs with water, freeze drying the GOABs, and, optionally, reducing the graphene oxide of the GOABS; and (2) a device comprising the GOABs, where the device is an electromagnetic interference (EMI) shielding film, a solar still, or a thermal management pack.
