Abstract
In the past decades, multi-functional materials have attracted significant attention for applications in electromagnetic interference (EMI) shielding, thermal management, and intelligent sensing. Extensive efforts have focused on developing conductive composites with enhanced functional performance, increasing evidence indicates that the structural characteristics of conductive networks plays a decisive role in determining material properties. Among various structural engineering strategies, oriented conductive networks have emerged as the highly effective platform for optimizing charge transport, heat transfer, and electromagnetic wave attenuation through the deliberate alignment of functional fillers. Unlike isotropic networks, oriented architectures provide new opportunities for achieving high performance with reduced filler loading by forming anisotropic transport pathways,. This review systematically summarizes recent advances in multi-functional materials based on oriented conductive networks, with particular emphasis on the underlying structure–property relationships governing sensing, EMI shielding, and thermal management performances. The effects of filler characteristics, orientation degree, and structural features on functional properties are critically analyzed. More importantly, this review highlights oriented conductive networks as a universal structural design strategy for multifunctional materials and discusses emerging opportunities associated with advanced fabrication technologies, AI-assisted materials design, and integrated material–structure engineering. Finally, the remaining challenges and future perspectives regarding scalability, structural precision, reliability, and multifunctional integration are discussed to guide the future development of next-generation multifunctional composites.
