Abstract :
DSC and dielectric DRS and TSDC measurements in PDMS/silica and PDMS/titania nanocomposites reveal the presence of several contributions to segmental dynamics and the corresponding glass transition. Further work is needed to clarify as to whether this behavior is common to rubber nanocomposites, in relation to the high flexibility of the polymer backbone.
