Abstract

Over the last two decades, supramolecular chemistry has seen remarkable advancements and has emerged as a powerful tool for designing dynamic materials. While its impact is well recognized in related research fields, its full potential in solid-state soft materials remains underexplored. Our group has been working to unlock the potential of supramolecular chemistry in soft materials. In this presentation, I will discuss our insights and approaches to developing mechanically robust polymer networks and polymer composites. In the first part, I will focus on the rational design principles of polymer networks crosslinked by supramolecular interactions to create high-performance elastomers with exceptional stretchability, toughness, and self-healing capabilities. Additionally, I will introduce a novel type of 3D printing photoresin for additive manufacturing applications. In the second part, I will highlight new assembly methods for integrating nanomaterials into polymer matrices, a critical aspect of maximizing the properties of both components. Two examples will be presented: (1) the acoustic assembly of liquid metal droplets in a polymer matrix to achieve rubber-like elastic conductors, and (2) template-directed assembly of conductive polymers within hydrogel matrices to develop tissue-like bioelectrode materials. Throughout the presentation, I will discuss not only the design of these materials but also their unique applications, showcasing how supramolecular chemistry can drive innovation in soft materials.
