Abstract

The molecular mobility of poly(phenylene oxide) nanocomposites with endometallofullerene at a concentration of 0.1, 0.5, and 1.0 wt % is studied by dielectric spectroscopy. Two processes of dipole polarization relaxation in the glassy state (β-process) and in the rubbery state (α-process) are found. It is shown that the molecular mobility of the β-process related to the presence of a nanoadditive does not change with concentration. Molecular mobility in the region of the α-process, which is associated with segmental mobility, shows a downward trend.

基于聚苯醚和内金属富勒烯的纳米复合材料的介电弛豫

摘要

通过介电谱研究了聚内苯撑富勒烯与聚苯醚纳米复合材料在0.1、0.5和1.0 wt%浓度下的分子迁移率。发现在玻璃态(β-过程)和橡胶态(α-过程)下偶极极化弛豫的两个过程。已经表明,与纳米添加剂的存在相关的β过程的分子迁移率不会随浓度而变化。与节段迁移率相关的α过程区域中的分子迁移率呈现下降趋势。
