چکیده:

When the polymer chains are sandwiched between two parallel solid surfaces, they show glass transition behaviour that deviates significantly from their bulk performance [1]. On the other hand, crosslinks can modify the segmental relaxation of polymer networks. In this work, the combined effects of nanoscale confinements imposed by crosslinking and intercalation on glass transition behaviour of PMMA-layered silicate (LS) nanocmposite networks is studied using thermal analysis investigations.
