| 摘 要： | 目前,人工骨由于力学性能不佳在应用上受到极大的限制,因此,如何在保证人工骨具有压电性能和生物性能的前提下提高其力学性能成为了研究热点。本文以钛酸钡-羟基磷灰石(BT-HA)复合材料为基体,质量分数为5%的碳纤维(Cf)作为增强体,利用传统固相烧结法制备了Cf/BT-HA复合材料,目的是在保证电学性能不变的前提下提高复合材料的力学性能。结果表明,BT-HA复合材料中加入Cf后,电学性能基本保持不变,力学性能得到了很大的提升。样品具有较好的铁电性,压电常数d33为37 pC/N,居里温度为170 ℃,高于人工骨的使用温度。抗弯强度达到121.7 MPa,硬度达到3.56 GPa,均增大到未加Cf样品的3倍,断裂韧性增加了1倍,达到1.21 MPa·m1/2。Cf/BT-HA复合材料没有细胞毒性且骨诱导性良好,有望应用于骨替代材料领域。

| Abstract: | At present, the application of artificial bone is greatly limited due to its poor mechanical properties. Therefore, it has become a research interest to obtain the artificial bone with improved mechanical properties, while its original piezoelectric and biological properties are maintained. In this paper,in order to improve the mechanical properties of the composite while keeping the electrical properties unchanged, the carbon fiber/barium titanate-hydroxyapatite (Cf/BT-HA) composite was prepared by traditional solid-phase sintering method using barium titanate-hydroxyapatite (BT-HA) composite as matrix and carbon fiber (Cf) with 5% (mass fraction) as reinforcement.The results show that the electrical properties remain unchanged and the mechanical properties are greatly improved after adding Cf into the composite. The samples possess excellent ferroelectric properties, the piezoelectric constant d33 is 37 pC/N, and the Curie temperature is 170 ℃, which is higher than the artificial bone service temperature. The bending strength is 121.7 MPa, and the hardness is 3.56 GPa, both of which are three times of the original. The fracture toughness is also doubled, reaching 1.21 MPa·m1/2. Cf/BT-HA composites have no cytotoxicity and good osteoinduction. It is found that Cf/BT-HA composites would be a promising bone substitute material. |
