摘要

通过将介孔生物玻璃(MBG)和四氧化三铁(Fe_3O_4)纳米颗粒复合制备出Fe_3O_4/MBG复合骨水泥,并详细研究了Fe_3O_4纳米颗粒的添加对骨水泥凝结时间、抗压强度、生物活性、降解性能以及磁热性能的影响。研究结果表明,Fe_3O_4/MBG骨水泥具有较好的抗压强度,随着Fe_3O_4纳米颗粒量的增加,Fe_3O_4/MBG骨水泥的凝结时间延长、磁热性能提高,但几乎没有对骨水泥的生物活性和降解性能产生影响。
        Magnetite/mesoporous bioglass( Fe_3O_4/MBG) composite cements were successfully prepared by the addition of Fe_3O_4 nanoparticles into MBG cements. The effects of the Fe_3O_4 nanoparticles addition on the setting time,compressive strength,bioactivity,biodegradability and magnetic heating ability were investigated. The results showed that the Fe_3O_4/MBG cements had good compressive strength,and exhibited the prolonged setting time and enhanced magnetic heating ability with increasing Fe_3O_4 nanoparticles content. However,the Fe_3O_4 addition had little effect on the bioactivity and biodegradability.
