This study supports the binary and ternary merging tactic, this methodology is useful in the creation of new features that lacked in the parent constituents. Ra develops to reach its peak of 4.25 nm upon HAP/Sb2O3/GO which is shadowed by HAP/Sb2O3 with 3.87 nm. EDX technique offers quantitative, and qualitative elemental composition of the studied composite, where C, O, P, Ca, and Sb elements records 17.14, 66, 8.7, 7.57, and0.58%, respectively. Consequently, the composition is pure. Also, The BET technique’s resultant surface area is 39.49 for HAP/Sb2O3, and 50.76 m2/g for HAP/Sb2O3/GO. Additionally, The (HAP/GO, and HAP/Sb2O3/GO) ceramic composites microhardness was 3.2 ± 0.2 GPa for binary composite, and 3.5 ± 0.3 GPa for ternary composite. Thus, GO nano-materials enhance mechanical behavior. Applicably, the merging of the three components in one ternary nanocomposite presents the highest viability with 98.4 ± 0.8%, besides the highest antibacterial performance by 15.2 ± 0.4 mm for Escherichia coli and 16.1 ± 0.5 mm for Staphylococcus aureus.

用于生物医学应用的羟基磷灰石/氧化锑/氧化石墨烯混合体系的医学适用性的改进

这项研究支持二元和三元合并策略,这种方法可用于创建父组件中缺乏的新功能。Ra 在 HAP/Sb 2 O 3 /GO上达到 4.25 nm 的峰值,HAP/Sb 2 O 3被3.87 nm遮蔽。EDX 技术提供了所研究复合材料的定量和定性元素组成,其中 C、O、P、Ca 和 Sb 元素分别记录为 17.14、66、8.7、7.57 和 0.58%。因此,该组合物是纯的。此外,BET 技术的合成表面积对于 HAP/Sb 2 O 3 为 39.49,对于 HAP/Sb 2 O 350.76 m 2 / g/去。此外,二元复合材料的(HAP/GO和HAP/Sb 2 O 3 /GO)陶瓷复合材料的显微硬度为3.2±0.2 GPa,三元复合材料的显微硬度为3.5±0.3 GPa。因此,GO纳米材料增强了机械性能。可应用的是,三种成分在一种三元纳米复合材料中的融合表现出最高的生存能力,为 98.4 ± 0.8%,此外,大肠杆菌的最高抗菌性能为 15.2 ± 0.4 mm,金黄色葡萄球菌的最高抗菌性能为16.1 ± 0.5 mm 。
