Hybrid Conductive Polymers: Synthesis, Properties, and Multifunctionality

Conductive polymeric composites (CPCs) have been highlighted for various applications such as human health monitoring, wearable sensors, flexible devices, and electrical self-heating composites. Many electrically conductive fillers, e.g., carbon nanotubes (CNTs), carbon fibers (CFs), graphene nanopowder (GNP), or nanowires (NWs), can be used to induce conductivity in soft, flexible, or stretchable polymers. However, the CPCs fabricated with one type of electrically conductive filler sometimes show drawbacks in their performance during the service life. Hence, many studies have focused on hybrid CPCs having two types of conductive fillers to investigate their synergic effects on performance, multifunctionality, and stability enhancement compared to the conventional CPCs. In this regard, this chapter covers the synthesis and properties of different hybrid CPCs incorporating multiple conductive fillers. The synergic effects on the performance enhancement and multifunctionality of CPCs are also discussed.
