“…to glass transition). On the other hand, Pissis and coworkers have suggested that the interfacial polymer is not completely immobile, since it demonstrates retarded dynamics, as recorded via an additional relaxation process, as compared to the bulk [8,9,16,17]. Moreover, they proposed that the increased interfacial layer thickness in polydimethylsiloxa ne(PDMS)/titania as compared to PDMS/silica nanocomposites [8,9,18] originates from the stronger particle-polymer hydrogen bonding.…”
