摘要

摘要本研究介绍了一种制造具有复杂内部空隙的多孔碳结构的方法。三维打印聚乳酸作为内部牺牲模板，结合碳化乳清粉作为多孔碳基质。在 150°C 的温度下烧结乳清粉可获得固体块，碳化后可形成高多孔碳物体，同时保持原始模具形状。温度控制可确保在聚乳酸熔化之前成功烧结乳清粉。使用聚乳酸牺牲模板和乳清碳化，可以开发出具有精细定制内部空隙的装置，这一点已通过一个具有多孔碳壁的双阿基米德螺旋反应器得到证实。图表摘要

Fabrication of a stacked Archimedean spiral reactor with porous carbon walls using 3D-printed PLA as internal sacrificial template and carbonized whey powder as porous carbon matrix

Abstract

This study introduces a method to create porous carbon structures with intricate internal voids. 3D-printed PLA acts as an internal sacrificial template, combined with carbonized whey powder as the porous carbon matrix. Sintering whey powder at 150°C yields solid pieces that, upon carbonization, result in highly porous carbon objects while maintaining the original mold shape. Temperature control ensures successful whey powder sintering before PLA melting. The use of PLA sacrificial templates, along with whey carbonization, allows for developing devices with finely tailored internal voids, as demonstrated through a double Archimedean spiral reactor with porous carbon walls.
