▎ 摘　　要

NOVELTY - A material enclosing multiple cells, is produced by processes including water extraction from a graphene oxide structure and additive manufacturing, in which each cell contains a significant 5 degrees of vacuum, where for a given mass of material, the material occupies more volume than an equal mass of air at the atmospheric pressure. USE - As a material enclosing multiple cells (claimed), used in aeronautics and structural engineering; aircraft, drones, and small scale (including nano-scale) applications, including indoors or in other environments; geostationary and other mobile or immobile applications; and in a 3D-printer. ADVANTAGE - The material decreases power required for flight; reduces power generation resource consumption; decreases carbon dioxide (CO2) emissions from power generation; improves lifting medium for lighter than air craft, as the mass of helium and/or hydrogen is more than that of vacuum; simplifies the construction and use of permanently or semipermanently aloft craft, platforms, tools, agents, drones, structures, and buildings for an almost unlimited variety of purposes; and enhances resistance to atmospheric pressure, and minimizes the effect of any localized damage.
