Abstract:This study explored a visible light-based 3D printing technology for the fabrication of conductive polymer resin materials. A mixture of light-curable resin and multi-walled carbon nanotube （MWCNT） was used as the substrate， and the dispersibility of MWCNT was improved by adding nanocelluloses （CNF） to achieve the best electrical conductivity and printing quality of the hybrid resin. In addition， light curing， pyrolysis， and chemical activation were combined to form carbon electrodes with designable hierarchical pore structures. The electrodes had pore structures with a distribution from millimeter to micron to nanometer scale， and assembled symmetric supercapacitors were provided a high energy density of 0.91 mWh/cm2.
