摘要
本文将表面附着羟基基团的BaTiO3纳米粒子或MWCNTs均匀分散到聚醚酮酮(PEKK)基体中,用以改善其介电性能;在添加单种填料的基础上,同时添加BaTiO3和MWCNTs以获取性能更优的复合材料.结果表明,在PEKK中分别添加20 wt％含量的BaTiO3或5 wt％含量的MWCNTs时,复合薄膜各获得一最佳介电常数(εr)值;在添加20 wt％含量的BaTiO3的同时再添加7 wt％含量的MWCNTs时,复合薄膜得到一更佳的εr值.
Abstract
In this work,surface-modified barium titanate(BaTiO3)nanoparticles with hydroxyl groups or multi-walled carbon nanotubes(MWCNTs)were uniformly dispersed into the polyetherketoneketone(PEKK)matrix to enhance its dielectric properties.Moreover,in addition to adding a single type of filler,a combination of both BaTiO3 and MWCNTs was attempted to achieve composite materials with superior performance.Results showed that when 20 wt％of BaTiO3 or 5 wt％of MWCNTs were added to PEKK,the composite films achieved optimal values of relative permittivity(εr).More specifically,when 20 wt％of BaTiO3 was combined with 7 wt％of MWCNTs,the PEKK composite film exhibited an even better εr value than either filler alone.
