摘要:本研究探索了基于光固化的3D打印技术制造导电聚合物树脂材料。以可光固化树脂和多壁碳纳米管（MWCNT）混合物为基底，通过添加纳米纤维素（CNF）来改善MWCNT的分散性，使混合树脂达到最佳的导电性能和印刷质量。此外，结合了光固化、热解和化学活化等反应过程，形成可设计的分级孔结构的碳电极，该电极具有从毫米级到微米级再到纳米级分布的孔隙结构，组装对称超级电容器可提供高能量密度0.91 mWh/cm²。

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.
