Viscoelastic properties and reinforcement of non-aggregated and aggregated nanocompositest
We investigate the properties of polymer nanocomposites consisting of narrow disperse sphericalnanoparticles that are coated with narrow disperse polymers. These nanoparticles can be homogeneouslydispersed in a polymer matrix. The structure of the polymer-coated nanoparticles was examinedby using sm...

We investigate the properties of polymer nanocomposites consisting of narrow disperse sphericalnanoparticles that are coated with narrow disperse polymers. These nanoparticles can be homogeneouslydispersed in a polymer matrix. The structure of the polymer-coated nanoparticles was examinedby using small angle X-ray scattering (SAXS) and transmission electron microscopy (TEM), and wasrelated to the viscoelastic properties of the nanocomposites. We observe a systematic retardation of thepolymer relaxation dynamics with increasing particle loading. Nanoparticle aggregation leading to theformation of chain-like structures causes a strong reinforcement effect |
