Conductivity and Breakdown Properties on Cross-linked Polyethylene / Montmorillonite Nanocomposites
摘要
Abstract
In order to investigate the dispersion effect of nano montmorillonite on the conductivity and dielectric breakdown properties of composite,a series of cross-linked polyethylene/montmorillonite nanocomposites in the absence of compatililizers and in the presence of different compatililizers (vinyl acetate copolymer (EVA) or ethylene-ethyl acrylate (EEA)) were prepared by a melting blending method.Moreover,the layer spacing changes of organic montmorillonite(OMMT) in the polymer were studied.It is shown that the dispersion of OMMT in matrix resin depends on how the compatibilizer matches with the organic intercalants.The conductivity-temperature characteristic and the AC breakdown strength are used to characterize the dielectric property.It is demonstrated that the conductivity of nanocomposites increases with the rise of temperature.The extent of the increase depends on the intercalated efficiency of PE chain into the different organic OMMT.The nanocomposites have smaller data dispersion with the addition of OMMT which changes the internal structure of polymer,and the interface state generated by the uniformity of intercalating dispersion is the main factor which influencing the breakdown strength of nanocomposites.关键词
