Abstract

Mg-based alloys have several suitable properties for biomaterials, but they have major problems of being less antibacterial and have a low mechanical strength. To solve these problems, a new combination of Ag/Zn/Mg was prepared in this study, where the presence of Zn and Ag can help to increase the bioactivity. The use of 5 wt.% polymers consisting of PolyCaproLactone (PCL), PolyHydroxyButyrate (PHB) and PolyVinylTriMethoxySilane (PVTMS) is also investigated. DSC, XRD, TEM, FTIR, SEM, and EDAX analysis, as well as mechanical and bioactive behavior, were investigated to characterize the prepared composites. In the comparison, the best behavior was found when PHB was used. The results show that the strength values ranged from ~201 to 261 MPa.

摘要

镁基合金具有一些适用于生物材料的特性，但它们存在抗菌性较差和机械强度低的主要问题。为了解决这些问题，本研究制备了一种新的银/锌/镁组合，其中锌和银的存在有助于提高生物活性。还研究了使用由聚己内酯（PCL）、聚羟基丁酸酯（PHB）和聚乙烯基三甲氧基硅烷（PVTMS）组成的5 wt.%聚合物。通过差示扫描量热法（DSC）、X射线衍射（XRD）、透射电子显微镜（TEM）、傅里叶变换红外光谱（FTIR）、扫描电子显微镜（SEM）和能谱分析（EDAX），以及力学和生物活性行为研究，对制备的复合材料进行了表征。相比之下，使用PHB时表现出最佳性能。结果表明，强度值范围约为201至261兆帕。
