摘要:

以氧化锆为原材料,结合五组分黏合剂,自主制备了陶瓷粉末/聚合物复合丝材;然后利用陶瓷材料挤出成形技术(CME)制备了生坯试件;进而通过脱脂烧结工艺完成了高精度多孔ZrO2生物陶瓷支架的成形;最后通过实验表征了支架的物理属性、微观结构、力学性能及生物相容性等参数,揭示了CME制品工艺-结构-性能间的关联。研究结果表明:烧结支架试件密度达5.90~5.99 g/cm³(相对密度97.44%~98.99%),孔隙率稳定可控,且各向同性收缩有效避免了传统烧结的尺寸畸变;支架表面亲水性优异,力学性能与人体骨组织相匹配,且生物安全性良好(细胞活力大于60%)。

Abstract:

Zirconia was employed as the raw material, and ceramic powder/polymer composite filaments were fabricated by combining a five-component binder system. Green specimens were prepared using the CME technology, and high-precision porous ZrO2 bio-ceramic scaffolds were formed through a debinding and sintering process. The physical properties, microstructures, mechanics properties and biocompatibility of the scaffolds were experimentally characterized, and the relationships among processing, structure and properties of CME products were revealed. The results show that the densities of the sintered scaffold specimens range from 5.90 to 5.99 g/cm³ (97.44%~98.99% for relative densities), the porosities are stable and controllable, and isotropic shrinkage effectively avoids the typical dimensional distortions of conventional sintering. The scaffold surfaces exhibit excellent hydrophilicity, their mechanics properties match those of human bone tissues, and they demonstrate good biosafety, with cell viabilities exceeding 60%.

Key words: bio-ceramic material extrusion(CME), porous scaffold, physical attribute, mechanics property, biocompatibility
