Abstract

Textured piezoelectric ceramics have attracted significant attention due to their ability to achieve ultra-high piezoelectric properties comparable to single crystals at a lower cost. Traditional processing techniques, such as tape casting, can efficiently produce textured piezoelectric ceramics with simple structures but are inadequate for fabricating three-dimensional structures with high complexity, thereby limiting their applications in specific fields. Vat photopolymerization (VPP), an advanced additive manufacturing technology, can rapidly and accurately create intricate three-dimensional structures. Crucially, VPP can provide the necessary shear force to align the templates, resulting in the highly-textured piezoelectric ceramics. In this study, BaTiO₃-based piezoelectric ceramics with a high degree of texture (97.2 %) were produced using VPP technology. These ceramics exhibited a large piezoelectric coefficient (d₃₃ = 511 pC/N), which was 66 % higher than that of non-textured ceramics. Furthermore, textured ceramics with a honeycomb structure were fabricated, demonstrating their potential in sensing applications. This work confirms the feasibility of using VPP technology to prepare high-performance, complex-structured textured ceramics, thereby promoting the development and application of textured piezoelectric ceramics.

通过制绒和大桶光聚合实现三维蜂窝状结构的 BaTiO3 基压电陶瓷

纹理压电陶瓷能够以较低的成本获得与单晶体相媲美的超高压电特性，因而备受关注。传统的加工技术，如胶带浇铸，可以有效地生产结构简单的纹理压电陶瓷，但不足以制造复杂度较高的三维结构，因此限制了其在特定领域的应用。大桶光聚合（VPP）是一种先进的增材制造技术，可以快速、准确地制造出复杂的三维结构。最重要的是，VPP 可以提供必要的剪切力来对齐模板，从而产生高纹理压电陶瓷。在这项研究中，利用 VPP 技术生产出了具有高度纹理（97.2%）的基于 BaTiO3 的压电陶瓷。这些陶瓷表现出很大的压电系数（d33 = 511 pC/N），比无纹理陶瓷高出 66%。此外，还制造出了具有蜂巢结构的纹理陶瓷，证明了其在传感应用方面的潜力。这项工作证实了使用 VPP 技术制备高性能、复杂结构纹理陶瓷的可行性，从而促进了纹理压电陶瓷的开发和应用。
