Poly(ether ether ketone) (PEEK) is a high-performance thermoplastic with a distinctive combination of corrosion resistance, thermo-oxidative stability and outstanding physical and mechanical properties at high temperatures. A pertinent step forward in the development of this thermoplastic has been the inclusion of electrically conductive fillers to expand its functionality. In this review an overview of the research on electrically conductive PEEK composites is provided. Conductive filler type, fabrication methods, characterization details and different properties are described. Carbon nanotubes, graphene nanoplatelets and other organic and inorganic conductive fillers such as expanded graphite and nickel have been incorporated into PEEK by techniques such as extrusion, injection moulding and cold and hot compression moulding and in some cases with pre-processing steps including mechanochemical modifications in organic solvents. The influences of type, loading and compatibilization of fillers and processing conditions on the mechanical and electrical conductivity properties of the composites are analysed and compared. The incorporated fillers have been able to enhance the electrical conductivity of the PEEK composites to either the semiconducting or conductive regions. PEEK composites containing carbon nanotubes compatibilized by polysulfones and poly(ether imide) achieved electrical conductivity values in the semiconducting region at the lowest electrical percolation threshold of 0.1 wt%. Additionally, the inclusion of 10 wt% expanded graphite and 10 vol% inorganic macroparticles of nickel noticeably improved the electrical conductivity of PEEK into the conductive region. © 2021 The Authors.

导电聚醚醚酮材料综述

聚醚醚酮 (PEEK) 是一种高性能热塑性塑料，具有独特的耐腐蚀性、热氧化稳定性和出色的高温物理和机械性能。这种热塑性塑料开发的一个相关步骤是加入导电填料以扩展其功能。在这篇综述中，概述了导电 PEEK 复合材料的研究。描述了导电填料类型、制造方法、表征细节和不同的特性。碳纳米管、石墨烯纳米片和其他有机和无机导电填料（如膨胀石墨和镍）已通过挤出、注塑成型和冷热压缩成型，在某些情况下还有预处理步骤，包括在有机溶剂中进行机械化学改性。分析比较了填料的种类、负载量和相容性以及加工条件对复合材料机械和导电性能的影响。掺入的填料能够提高 PEEK 复合材料对半导体或导电区域的导电性。含有聚砜和聚（醚酰亚胺）相容的碳纳米管的 PEEK 复合材料在半导体区域中以 0.1 wt% 的最低电渗透阈值实现了电导率值。此外，包含 10 wt% 的膨胀石墨和 10 vol% 的镍无机大颗粒显着改善了 PEEK 进入导电区域的电导率。© 2021 作者。由 John Wiley & Sons Ltd 代表化学工业协会出版的Polymer International。
