Abstract

The effect of electrothermopolarization (ETP) on the structure and electrophysical properties (electret, dielectric) of polymer nanocomposites based on HDPE and hafnium oxide nanoparticles has been studied. The possibility of significant change in dielectric properties of HDPE/HfO₂ polymer nanocomposites at 3–7% nanoparticle concentration has been confirmed. The interactions of the polymer and nanoparticles are considered and the results of changes in the structure of HDPE/HfO₂ polymer nanocomposite in its volume and interphase zone before and after electrothermopolarization are presented. Spectroscopic studies of nanocomposites show that the introduction of nanoparticles is compatible in the presence of polyethylene. Results acquired via an optical microscope with magnification revealed that the nanocomposite HDPE/HfO₂ had a variety of morphology from oval, spherical, polygon, to irregular shapes depending on their snitches HDPE and HfO₂. HfO₂ affects the structure of the nanocomposites, which is observed by SEM, AFM, DSC and confirmed by infrared spectroscopy (FTIR).

电热极化过程对基于高密度聚乙烯和 HfO2 纳米粒子的纳米复合材料的结构和性能的影响

研究了电热极化（ETP）对基于高密度聚乙烯和纳米氧化铪的聚合物纳米复合材料的结构和电物理性质（驻极体、介电）的影响。研究证实，当纳米粒子浓度为 3%-7% 时，高密度聚乙烯/氧化铪聚合物纳米复合材料的介电性能可能会发生重大变化。研究考虑了聚合物和纳米粒子的相互作用，并给出了电热极化前后高密度聚乙烯/二氧化铪聚合物纳米复合材料在体积和相间区结构的变化结果。纳米复合材料的光谱研究表明，纳米粒子的引入与聚乙烯的存在是相容的。通过放大光学显微镜获得的结果显示，HDPE/HfO2 纳米复合材料的形态多种多样，从椭圆形、球形、多边形到不规则形，这取决于它们的缝隙 HDPE 和 HfO2。HfO2 会影响纳米复合材料的结构，这一点可通过扫描电镜、原子力显微镜和 DSC 观察到，并可通过红外光谱（FTIR）证实。
