The free-standing gyroid carbon network with a highly ordered and interconnected porous structure has been fabricated by impregnating the carbon precursor solution into the gyroid block copolymer nanotemplates and subsequently carbonizing them. A wide range of analytical tools have been employed to characterize fabricated porous carbon material. Prepared nanostructures are envisioned to have a great potential in myriad areas such as energy storage/conversion devices owing to their fascinating morphology exhibiting high surface area and uniform porosity with interconnected three-dimensional networks. The resulting carbon nanoporous structures infused with elemental sulfur have been found to work as a promising electrode for lithium sulfur batteries demonstrating a high cycling stability over more than 200 cycles. 2015-06-23 00:00:00 Prepared nanostructures surface area carbon precursor solution cycling stability lithium sulfur batteries uniform porosity gyroid carbon network nanoporous carbon cathodes Gyroid Block Copolymer TemplatesThis study reports 200 cycles gyroid carbon replicas 4VP Nanoporous Cathodes carbon material gyroid block copolymer nanotemplates carbon nanoporous structures
