Fabrication and microstructural characterization of pyrolytic carbon nanolattices. (A) Schematic illustration of the fabrication process of pyrolytic carbon nanolattices. (B and C) CAD rendition of an octet- and iso-truss unit cell. (D and E) SEM images of an octet nanolattice with a strut diameter of d = 435 nm and an iso-truss nanolattice fabricated with a vertical strut diameter of d₁ = 460 nm and a slanted strut diameter of d₂ = 523 nm. (F) An HRTEM image of pyrolytic carbon extracted from the nanolattice, which indicates an amorphous nature of the pyrolytic carbon. Initial detectable structural imperfections caused by fabrication process are circled in D and E.
