Herein, we used chemical precipitation method to synthesize cadmium sulfide (CdS) nanoparticles (NPs) with different concentrations of CdNO 3 . The CdS NPs of size 105 nm and the corresponding zeta potential of 42.2 mV were achieved at CdNO 3 concentration of 1 mM. X-ray diffraction (XRD) analysis revealed W-type hexagonal geometry of CdS NPs. The prepared CdS NPs were introduced into poly(hydroxybutyrate) (PHB) matrix to fabricate CdS/PHB composite nanomaterial. The physicochemical characterization showed successful synthesis of a novel nanocomposite. The XRD analysis showed that CdS/PHB nanocomposite exhibited hexagonal crystal structure, i.e., crystallite orientation of nanocomposite was majorly controlled by CdS NPs. Scanning electron micrographs of CdS NPs and CdS/PHB nanocomposite revealed spherical morphology of CdS NPs and their successful placement into PHB matrix with some random aggregations. The results were further confirmed using transmission electron microscopy (TEM) and a high-resolution TEM. Thermogravimetric analysis showed improved thermal characteristics of nanocomposites after incorporation of CdS NPs into PHB matrix.

硫化镉纳米颗粒的制备及其在聚羟基丁酸纳米复合材料中的介导

在此，我们使用化学沉淀法合成了具有不同浓度 CdNO 3 的硫化镉 (CdS) 纳米颗粒 (NPs)。在 1 mM CdNO 3 浓度下实现了 105 nm 大小的 CdS NP 和 42.2 mV 的相应 zeta 电位。X 射线衍射 (XRD) 分析揭示了 CdS NPs 的 W 型六边形几何形状。将制备的 CdS NPs 引入聚（羟基丁酸酯）（PHB）基质中以制备 CdS/PHB 复合纳米材料。物理化学表征表明成功合成了一种新型纳米复合材料。XRD分析表明CdS/PHB纳米复合材料呈现六方晶体结构，即纳米复合材料的微晶取向主要受CdS NPs控制。CdS NPs 和 CdS/PHB 纳米复合材料的扫描电子显微照片揭示了 CdS NPs 的球形形态和它们成功地放置到 PHB 基质中，并具有一些随机聚集。使用透射电子显微镜 (TEM) 和高分辨率 TEM 进一步证实了结果。热重分析表明，将 CdS NPs 掺入 PHB 基质后，纳米复合材料的热特性得到改善。
