Study on the Icosahedral Fullerene Structure with Ultra-light and Pressure Resistance Characters
An ultra-light icosahedral fullerene structure is designed in this paper. It has 12 pentagonal faces at the vertices of regular icosahedron and the 20 triangular faces which are expanded by hexagonal faces that consist of carbon atoms. When its size exceeds a critical value, the density of the icosahedron becomes less than the air. Since the hollow structure will be deformed under the atmospheric pressure, we propose to charge helium atoms to obtain a floatable icosahedral fullerene with pressure resistance character. According to the requirements, the radius of the midpoint ball of the edge is 493.33 μm, the total density of the structure which is filled with helium is 0.18 kg/m3, and the buoyancy per cubic meter in the air is 10.88 N. Theoretical calculation and simulation are combined to explore a new way for ultra-light materials.
