Abstract
Recently, an unusual and unique property was observed in polymer nanocomposite systems by Senses et al. (Senses, E.; Isherwood, A.; Akcora, P. ACS Appl. Mater. Interfaces 2015, 7, 14682). These nanocomposite systems show stiffening behavior upon heating that is reversible and repeatable. This unique thermal stiffening behavior was attributed to the dynamic coupling of high glass transition (Tg) grafted chains and low-Tg matrix chains. To better study the stiffening mechanism, we first studied the viscoelasticity and dynamics of a model dynamically asymmetric binary polymer blend which consists of two type of chains with significantly different Tg.
