Interfacial Dynamics Controlled Dispersion and Physical Properties of Polymer Nanocomposites

Polymer nanocomposites exhibit complex behaviors arising from filler–polymer interactions, nanoparticle dispersion, and interfacial dynamics across multiple length and time scales. In particular, interfacial adsorption, particle-network formation, and processing-induced nonequilibrium states play critical roles in determining the rheological, mechanical, and transport properties of these materials. However, establishing quantitative relationships among interfacial structure, dynamics, and macroscopic properties remains a significant challenge.

Our research aims to uncover the fundamental principles that connect filler–polymer interactions, nanoparticle organization, and material dynamics in polymer nanocomposites. By combining advanced scattering techniques, dielectric spectroscopy, and rheological measurements, we investigate equilibrium and nonequilibrium structures, relaxation dynamics, and dynamic heterogeneity from the molecular scale to mesoscale particle networks.

Through these studies, we seek to establish a unified framework linking interfacial interactions, nonequilibrium dynamics, and macroscopic properties, enabling the rational design of next-generation polymer nanocomposites.
