SMNP Group aims to establish a fundamental understanding of soft materials by bridging molecular interactions, interfacial dynamics, and macroscopic properties across multiple length and time scales. We specialize in the quantitative characterization of complex soft matter systems using advanced scattering techniques, coupled with rheological and dynamic analyses, to uncover structure–property–processing relationships. 1) Sustainable and recyclable polymer systems,  2) In-depth and AI-assisted analysis of polymer dynamics and nanorheology, 3) Polymer nanocomposites for next-generation semiconductor packaging, including thermal interface materials and high-performance composites, 4) Structure and dispersion of battery slurries for energy storage systems, focusing on particle–polymer interactions, microstructure control, and rheology-driven processing, 5) Energy-related soft materials, including battery slurry design and electrode fabrication processes. Polymer nanocomposites (PNCs) are hybrid materials that incorporate polymers and functional nanofillers. They have been very widely used in industrial/daily products, due to their enhanced properties such as electrical, optical, mechanical, thermal properties compared to pristine polymers. Our research group is interested in understanding of interfacial layers based on particle-polymer interactions and controlling the structures to produce desired properties in complex nanoparticle-polymer composites. Processing conditions of PNC such as casting solvent can greatly impact the characteristics of interfacial polymer layer around nanoparticle surface, making PNCs be in nonequilibrium states. As a result, PNC properties can be significantly changed by initial solvent although it does not exist in the final state, thus, requiri
