Theoretical analysis for enhancing percolation characteristic in Nanomaterials design

Recent advances in strategies for soft materials have drawn attention for developing wearable and bioelectronics, transitioning them from rigid to soft systems. This shift offers significant advantages, particularly in mechanical compatibility with human tissues. Among these materials, conductive nanocomposites stand out as essential components, serving as conductive interconnects in stretchable electronic systems. Despite notable progress, optimizing conductive nanocomposites to enhance performance while preserving their mechanical properties remains a significant challenge. In this study, we explore the key parameters influencing the performance of conductive nanocomposites through both qualitative and quantitative analyses. We begin by summarizing recent advancements in metallic nanocomposites and then delve into the three-dimensional percolation theory, which provides a theoretical foundation for understanding the random systems of nanocomposites. Additionally, we identify critical parameters that can modulate the percolative connections of nanoparticles inside of soft elastomer matrix. Finally, we discuss the potential applications of optimized conductive nanocomposites, with a focus on wearable and bio-implantable systems. The article concludes with a brief summary and a discussion of the remaining challenges in this field.
