Fabrication and analysis of mechanical properties of 3D nanoarchitecture glassy carbon

Abstract

In general, a material has a property in which density and strength are proportional, so that a material with high strength has a high density, and a material with low strength has a low density. However, in the case of a porous material, it is possible to minimize a decrease in strength compared to a decrease in density by efficiently controlling the distribution of pores inside. By combining the advantages of the nanoarchitecture with the properties of glassy carbon having high strength in the bulk scale, three-dimensional patterning was performed on the photoresist, and carbonized through pyrolysis. Through this process, three-dimensional nanoarchitecture glassy carbon was fabricated and mechanical properties were measured. In the case of the measured 3D nanoarchitecture glassy carbon, the mechanical strength was 7 to 10 times higher than that of general materials.
