摘要:

陶瓷基多孔结构既继承致密陶瓷材料耐高温、电绝缘、化学稳定的优异性能, 又兼具多孔结构低密度、高比表面积、低热导率的独特优势, 已被广泛应用于隔热、骨组织工程、过滤及污染物清除、电子元器件等领域。但是, 陶瓷基多孔结构的传统成孔方法在宏观尺度创造复杂几何外形与微纳尺度调控孔结构形态方面仍面临巨大挑战。近几十年来, 研究人员一直致力于创新陶瓷基多孔结构的加工成型方法, 以直写3D打印为代表的增材制造技术成为当前研究的热点, 并迅速发展出一系列成熟理论与创新方法。本文首先概述了陶瓷基多孔结构的传统成孔方法与增材制造成孔方法, 进一步详细介绍了直写组装成孔工艺过程, 主要包括假塑性墨水配方、固化策略、干燥及后处理, 分析了传统成孔方法与直写3D打印二者的组合技术在构筑陶瓷基多级孔结构方面的可行性, 总结了直写3D打印技术在制造复杂陶瓷基多孔结构领域的新观点、新进展和新发现, 最后结合陶瓷基多孔结构实际应用现状对直写3D技术的未来发展与挑战进行了展望。

Abstract:

Ceramic-based porous structures not only inherit the excellent properties of dense ceramic materials such as high-temperature resistance, electrical insulation, and chemical stability, but also have unique advantages similar to porous structures, including low density, high specific surface area, and low thermal conductivity. They show great potential in various applications, such as thermal insulation, bone tissue engineering, filtration and pollutants removal, and electronic components. However, there still exist some challenges for shaping complex geometries on the macro- scale and adjusting pore morphologies on the micro- and nano-scale through the conventional preparation strategy of ceramic-based porous structures. In recent decades, researchers have been devoting themselves to developing novel manufacturing techniques for ceramic-based porous structures. The direct-ink-writing 3D printing, as one of the representative additive manufacturing technologies, has become a current research hotspot, rapidly developing a series of mature theories and innovative methodologies for fabricating porous structures. In this work, the conventional strategies and additive manufacturing strategies for obtaining porous structures were firstly summarized. The direct-write assembly processes of pore structures were further introduced in detail, mainly including pseudoplastic ink formulation, solidification strategy, drying, and post-treatment. Meanwhile, the feasibility of direct-ink-writing 3D printing technologies combined with conventional manufacturing strategies in constructing ceramic-based hierarchical pore structures was analyzed emphatically. The new perspectives, developments, and discoveries of direct-ink-writing 3D printing technologies were further summarized in the field of manufacturing complex ceramic-based porous structures. In addition, the developments and challenges in the future were prospected according to the actual application status.
