We report the fabrication of lightweight porous carbon structures via UV-assisted photopolymerization molding using a commercial photocurable resin modified with natural tannin and sodium carboxymethyl cellulose (NaCMC) as sustainable additives. A systematic analysis was conducted by applying a Design of Experiments (DOE) approach and regression modeling to evaluate the effects of varying blend compositions on carbon yield and mechanical strength. The results indicate that increasing the tannin content led to a maximum carbon yield of 13.43%, with an average porosity of approximately 80% and a compressive strength around 1 kPa. NaCMC was found to effectively control the resin viscosity within printable limits of 0.2537 Pa·s, although NaCMC indirectly improved carbonization efficiency through normalized yield analysis. This work highlights the synergistic role of bio-based polymers in tuning porous carbon properties. The findings provide a data-driven framework for designing sustainable polymer-derived carbon materials, bridging additive manufacturing with green chemistry.
我们报告了通过紫外线辅助光聚合成型制备轻质多孔碳结构的方法，该方法使用了用天然单宁和羧甲基纤维素钠（NaCMC）改性的商用光固化树脂作为可持续添加剂。通过应用实验设计（DOE）方法和回归建模进行了系统分析，以评估不同共混物组成对碳产率和机械强度的影响。结果表明，单宁含量的增加导致最大碳产率达到13.43%，平均孔隙率约为80%，抗压强度约为1 kPa。发现NaCMC可有效地将树脂粘度控制在可打印的0.2537 Pa·s范围内，尽管NaCMC通过归一化产率分析间接提高了碳化效率。这项工作突出了生物基聚合物在调节多孔碳性能方面的协同作用。这些发现为设计可持续的聚合物衍生碳材料提供了一个数据驱动的框架，将增材制造与绿色化学联系起来。
