Dynamics of polymer thin films on different interface interaction |
| 초록 |
Polymer mobility of confined system has been studied by dewetting and diffusion dynamics measurements. Especially, the polymer mobility is greatly influenced by adjecent polymer layer. In this study, we mainly focused on the polymer-polymer interaction. First, the effect of attractive on the dewetting phenomenon was investigated by using graphene oxide (GO) sheets. when wrinkled GO was placed at the interface between poly(methyl methacrylate) (PMMA) and Si substrates, the dewetting behavior were inhibited due to the amphiphilic properties of GO. In the case of diffusion dynamics, we used repulsive wall (Polystyrene, PS) samples as a model composite system of diffusion. Polymer mobility of confined systems was measured by a neutron reflectivity technique. The diffusion dynamics was signitantly affected by neighboring surfaces which have eighter attractive or repulsive interaction with polymers. |
