Structure and dynamics of nonlinear polymer-nanoparticle composites

Abstract:
We have designed new types of nanocomposites and blend based on  well-defined non-linear polymer architectures and well-dispersed  nanoparticles. I will overview the key results we obtained from static  and dynamic neutron scattering, x-ray photon correlation spectroscopy  and bulk rheology, which help to uncover the distinct role of polymer  topology on (i) dynamics of polymers at nanoparticle interfaces, (ii)  nanoscale particle motion polymer matrices, and (iii) bulk rheological  reinforcement.

Mechanical enhancement and dynamics in polymer nanocomposites

Abstract:
Polymer nanocomposites have broad applications. The size, shape of nanoparticles, and their interaction with polymers determine the mechanical properties of polymer nanocomposites. In this talk, I will discuss the mechanical enhancement and dynamics at different time scales in model polymer nanocomposites using different polymer molecular weights, different particle sizes, and different surface properties of nanoparticles.
