Abstract

In the present investigation, solution casting method was used for the preparation of nanocomposite (NC) films. At first, the surface of ZrO nanoparticles (NPs) was modified with vitamin B (VB) as a bioactive coupling agent to achieve a better dispersion and compatibility of NPs within the poly(vinyl chloride) (PVC) matrix. The grafting of modifier on the surface of ZrO was confirmed by Fourier transform infrared spectroscopy and thermogravimetric analysis (TGA). Finally, the resulting modified ZrO (ZrO-VB), was used as a nano-filler and incorporated into the PVC matrix to improve its mechanical and thermal properties. These processes were carried out under ultrasonic irradiation conditions, which is an economical and eco-friendly method. The effect of ZrO-VB on the properties and morphology of the PVC matrix was characterized by various techniques. Field emission scanning electron microscopy and transmission electron microscopy analyses showed a good dispersion of fillers into the PVC matrix with the average diameter of 37-40 nm. UV-Vis spectroscopy was used to study optical behavior of the obtained NC films. TGA analysis has confirmed the presence of about 7 wt% VB on the surface of ZrO. Also, the data indicated that the thermal and mechanical properties of the NC films were enhanced.

摘要

在本研究中，采用溶液浇铸法制备纳米复合材料（NC）薄膜。首先，用维生素B（VB）作为生物活性偶联剂对ZrO纳米颗粒（NPs）的表面进行改性，以实现NPs在聚氯乙烯（PVC）基体中更好的分散和相容性。通过傅里叶变换红外光谱和热重分析（TGA）证实了改性剂在ZrO表面的接枝。最后，将所得的改性ZrO（ZrO-VB）用作纳米填料，并掺入PVC基体中以改善其力学和热性能。这些过程是在超声辐照条件下进行的，这是一种经济且环保的方法。通过各种技术表征了ZrO-VB对PVC基体性能和形态的影响。场发射扫描电子显微镜和透射电子显微镜分析表明，填料在PVC基体中分散良好，平均直径为37-40nm。紫外可见光谱用于研究所得NC薄膜的光学行为。TGA分析证实ZrO表面存在约7wt%的VB。此外，数据表明NC薄膜的热性能和力学性能得到了增强。
