Yielding Criterion of Double Network Hydrogels

Abstract:
Double network (DN) gels, consisting of the brittle first and the flexible second networks, have  been known as extremely tough hydrogels. In this talk, we will discuss  the relationship between yielding and the first network molecular  structure of DN gels.

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.
