Electrically Conductive Porous Carbon Structures Fabricated by Laser Direct Carbonization of Bamboo

Porous carbon structures have attracted much interest for applications, such as catalyst carriers, energy storage devices, and chemical sensors, due to their chemical stability, high adsorptive property, and electrical conductivity. Among several methods to fabricate porous carbon structures, laser carbonization is a promising method for spatially-selective and high-resolution fabrication of electrically conductive porous carbon strucutres [1], [2]. Recently, the fabrication of porous carbon structures by laser carbonization using biomasses, materials derived from living or recently-living organisms, as the precursor have been reported [3]. In this study, we fabricated electrically conductive porous carbon structures by the femtosecond-laser carbonization of bamboo, which is a biomass with a well-connected three-dimensional porous structure by nature.
