Abstract

In this paper, a novel polylactide-based nanocomposite with the addition of bentonite as a filler, Fusabond, and glycerine as a compatibilizer and plasticizer, were prepared and investigated. Four samples with different contents of bentonite (1, 5, 10, and 15 wt.%), as well as three samples without fillers, were prepared with an easily scalable method: melt blending. The electrical properties of all prepared samples were investigated with broadband dielectric spectroscopy in the frequency range between 0.1 Hz and 1 MHz. Measurements were conducted at nine temperatures between 293.15 and 333.15 K (20 to 60 °C) with steps of 5 K. It was found that the increase in the content of bentonite in polylactide has a significant effect on the electrical properties of the prepared nanocomposites.

摘要

在本文中，制备并研究了一种新型的聚乳酸基纳米复合材料，其中添加了膨润土作为填料、福斯曼（Fusabond）作为相容剂以及甘油作为增塑剂。采用易于扩展的方法——熔融共混，制备了四个含有不同含量膨润土（1%、5%、10%和15%重量）的样品，以及三个不含填料的样品。使用宽带介电谱在0.1 Hz至1 MHz的频率范围内研究了所有制备样品的电学性能。在293.15至333.15 K（20至60°C）之间的九个温度下进行测量，步长为5 K。结果发现，聚乳酸中膨润土含量的增加对所制备的纳米复合材料的电学性能有显著影响。
