13.1 Introduction

To date, several advanced materials have been developed in order to resolve the issue of electromagnetic interference (EMI). Among those materials, intrinsic conductive polymers, metal/polymer composites, and conductive filler/polymer composites (CPCs) are the most commonly used and extensively investigated. Metals and their polymeric composites presents high EMI shielding effectiveness, and thus dominate the EMI shielding materials. Being lightweight, processable, and corrosion resistant are important technical requirements for many EMI shielding applications [1, 2]. Intrinsic conductive polymers can well meet these requirements due to their inherent properties [35]. However, their low conductivity largely limited their shielding effectiveness. CPCs, which incorporate the aforementioned properties of polymers and high conductivity of the fillers, have attracted great interest in recent years [68].

Metal nanowires possess high conductivity and good flexibility. Furthermore, nanowires could form an interconnected network with high electrical conductivity at low percolation threshold in a polymer because of their high aspect ratio. Hence, metal nanowires/polymer composites would show great promise for EMI shielding. In previous studies, Ag [913], Au [14 ...
