糠醛衍生碳点单组分光引发剂实现高保真DLP 3D打印
One‐Component Carbon Dot Photoinitiator Enables High‐Fidelity Digital Light Processing 3D Printing With Improved Mechanical Resistance
AI 导读
研究团队将可光裂解的二苯基酰基膦氧化物接枝到糠醛衍生碳点表面，制得单组分碳点光引发剂CD-PO，用于引发丙烯酸酯单体光聚合。与DLP常用的TPO相比，CD-PO通过优化光固化深度实现微米级打印精度，光固化网络的韧性约为TPO固化网络的4.6倍，且组分迁移减少、生物安全性改善。CD-PO在低强度UV-LED和空气条件下仍保持较高光反应活性。
推荐理由
以生物基碳点替代TPO作单组分光引发剂，同时给出打印精度、韧性与迁移性的对比数据。
创新点
把可光裂解的酰基膦氧化物接枝到生物基碳点上，做成无需外加助剂的单组分光引发剂，同时兼顾固化深度控制与纳米复合增韧。
