In the domain of photopolymerization-based additive manufacturing (3D vat printing), ceramic photopolymer resins represent a multifaceted composite, predominantly comprising oligomers, ceramic fillers, and photoinitiators. However, the synergy between the ceramic fillers and polymer matrix, along with the stabilization and homogenization of the composite, is facilitated by specific additives, notably surface-active agents, dispersants, and adhesion promoters. Although these additives constitute a minor fraction in terms of volume, their influence on the final properties of the material is substantial. Consequently, their meticulous selection and integration are crucial, subtly guiding the performance and characteristics of the resultant ceramic matrix composites toward enhancement. This review delves into the array of dispersants and coupling agents utilized in the additive manufacturing of ceramic components. It elucidates the interaction mechanisms between these additives and ceramic fillers and examines how these interactions affect the additive manufacturing process. Furthermore, this review investigates the impact of various additives on the rheological behavior of ceramic slurries and their subsequent effects on the post-manufacturing stages, such as debinding and sintering. It also addresses the challenges and prospects in the optimization of dispersants and coupling agents for advanced ceramic additive manufacturing applications.
在基于光聚合的增材制造（3D 槽式打印）领域，陶瓷光聚合树脂是一种多方面的复合材料，主要由低聚物、陶瓷填料和光引发剂组成。然而，陶瓷填料与聚合物基体之间的协同作用，以及复合材料的稳定化和均匀化，是由特定添加剂促成的，特别是表面活性剂、分散剂和粘结促进剂。尽管这些添加剂在体积方面占比很小，但它们对材料最终性能的影响却很大。因此，对它们进行精心选择和整合至关重要，这会巧妙地引导所得陶瓷基复合材料的性能和特性朝着提升的方向发展。本综述深入探讨了用于陶瓷部件增材制造的一系列分散剂和偶联剂。它阐明了这些添加剂与陶瓷填料之间的相互作用机制，并研究了这些相互作用如何影响增材制造过程。此外，本综述还研究了各种添加剂对陶瓷浆料流变行为的影响，以及它们随后对诸如脱脂和烧结等制造后阶段的影响。它还探讨了在先进陶瓷增材制造应用中优化分散剂和偶联剂所面临的挑战和前景。
