In this project, physicochemical properties of poly(vinyl chloride) (PVC) reinforced by ZnO nanoparticles (NPs) were studied. Firstly, ZnO NPs were modified with bovine serum albumin (BSA) as an organo-modifier and biocompatible substance through ultrasound irradiation as environmental friendly, low cost and rapid means. Nanocomposite (NC) films were prepared by loadings of various ratios of ZnO/BSA NPs (3, 6 and 9wt%) inside the PVC. Structural morphology and physical properties of the ZnO-BSA NPs and NC films were investigated via Fourier transform infrared spectroscopy, X-ray diffraction, thermogravimetric analysis (TGA), transmission electron microscopy and field emission scanning electron microscopy. According to the obtained information from the TGA, an increase in the thermal stability can be clearly observed. Also the results of contact angle analysis indicated with increasing percent of ZnO/BSA NPs into PVC the hydrophilic behaviors of NCs were increased.
在这个项目中，研究了氧化锌纳米粒子（ZnO NPs）增强聚氯乙烯（PVC）的物理化学性质。首先，通过超声辐射，将 ZnO NPs 用牛血清白蛋白（BSA）进行改性，作为一种有机改性剂和生物相容性物质，这是一种环保、低成本和快速的方法。通过在 PVC 内部负载不同比例的 ZnO/BSA NPs（3、6 和 9wt%）制备纳米复合材料（NC）薄膜。通过傅里叶变换红外光谱、X 射线衍射、热重分析（TGA）、透射电子显微镜和场发射扫描电子显微镜研究了 ZnO-BSA NPs 和 NC 薄膜的结构形貌和物理性能。根据 TGA 获得的信息，明显观察到热稳定性的提高。此外，接触角分析的结果表明，随着 ZnO/BSA NPs 在 PVC 中百分含量的增加，NC 的亲水行为增加。
