Abstract

In this work, hybrid reinforced epoxy biopolymer composites were developed using natural hydroxyapatite and zinc oxide (nHAp/ZnO). The epoxy was reinforced with varying addition of nHAp and ZnO in the steps of 3, 5 and 7 wt. % respectively using stir casting molding process. The developed composites were immersed in simulated body fluid (SBF) at 37oC to determine their bioactivity. Microstructure evaluation using scanning electron microscopy was also used to assess the morphology of the developed composites before and after in vitro test, respectively.The microstructure evaluation in vitro showed good deposition of white-like layers on the surface indicating good bioactivity reaction with the SBF and affirm that the developed biopolymers will react well with living tissue when used in vivo. However, hybrid sample BP5HB showed better apatite-like layer deposition.
用于牙科的羟基磷灰石/氧化锌杂化增强生物基环氧树脂复合材料的生物活性特性和形态特征
这项研究利用天然羟基磷灰石和氧化锌(nHAp/ZnO)开发了混合增强环氧生物聚合物复合材料。采用搅拌铸造成型工艺,以 3、5 和 7 wt. % 的比例添加不同的 nHAp 和 ZnO 来增强环氧树脂。将开发的复合材料浸入 37oC 的模拟体液 (SBF) 中,以确定其生物活性。体外微观结构评估结果表明,复合材料表面有良好的白色沉积层,这表明复合材料与 SBF 具有良好的生物活性反应,并肯定了所开发的生物聚合物在体内使用时将与活体组织产生良好的反应。不过,混合样品 BP5HB 的磷灰石样层沉积效果更好。
