摘要

使用介电光谱和直流介电击穿强度测量研究了将二甲苯引入含有聚乙烯、乙烯和乙酸乙烯酯的共聚物以及有机粘土的复合体系中的介电效应,可以根据X射线衍射数据来理解。在介电光谱中,尽管有机粘土单独改变了聚合物共混物的介电响应,二甲苯对未填充的聚合物共混物没有影响,但当二甲苯和有机粘土都存在时,在1 Vrms振幅电压,用于获取介电数据。与此相反,在DC中,介电击穿强度测量显示,在高场条件下,二甲苯和有机粘土都独立地导致击穿强度降低。开展这项工作是为了检验不稳定、低摩尔质量杂质对可通过溶剂路线处理的类似系统的电性能可能产生的影响的普遍性。

Influence of xylene on the dielectric response of an organoclay-containing nanocomposite

The dielectric effect, investigated using dielectric spectroscopy and DC dielectric breakdown strength measurements, of introducing xylene into a composite system containing polyethylene, a co-polymer of ethylene and vinyl acetate and an organoclay can be understood in light of X-ray diffraction data. In dielectric spectroscopy, although organoclay alone changes the dielectric response of the polymer blend and xylene has no effect on the unfilled polymer blend, when both xylene and organoclay are present, a synergistic response is revealed at the 1 Vrms amplitude voltage used to acquire the dielectric data. In contrast to this, in DC, dielectric breakdown strength measurements revealed that, under high field conditions, both the xylene and organoclay, independently, caused a decreased breakdown strength. This work was undertaken in order to examine the generality of the possible effects of labile, low molar mass impurities on electrical properties of comparable systems, which may be processed through solvent-based routes.
